System Simulation

ANSYS medini analyze fully supports Failure Mode and Impact Analysis (FMEDA) at the semiconductor level, including verification of safety mechanism coverage data by faults. This allows you to comply with the requirements of ISO 26262:11 2018. For hardware reliability analysis, medini analyze supports fault rate calculation based on IEC 61709 data. Configuration management, as required by security standards, has been simplified through the CLI to provide seamless integration of medini analyze with the user configuration management system (SVN, git, PTC, etc.).

ANSYS Twin Builder enhances the capabilities and process of inserting and editing components of Modelica libraries into the system model. Add-ons include support for Undo/Redo and connector array in the dialog box. In addition, the performance of the solver in Twin Builder is increased to 30 percent. Dynamic reduced-order model (ROM) builder supports models with an unlimited number of I/Os implemented using the singular decomposition method (SVD) and selecting its most dominant modes. The user can also build models in Dynamic ROM builder with partial selection of inputs/outputs, Ansys claims.

Using GPU-based rendering, you can work interactively with SPEOS models and quickly get results in ANSYS VRXPERIENCE. According to the developer, his intuitive user interface allows you to easily change materials, colors, lighting or viewpoint properties during the modeling process with the simple action "drag and drop."

The ANSYS VRXPERIENCE Sound software complex adds another dimension to the toolkit - acoustics modeling. With this solution, you can listen to and change sound coming from an audio recording, CAE system, or VR environment. ANSYS VRXPERIENCE Sound - a comprehensive solution for sound analysis, sound quality measurement and playback in 3D integrates with ANSYS Mechanical.

In the ANSYS driving modeling platform, you can calculate feedback ADAS systems and test scenarios of autonomous driving using ANSYS VREXPERIENCE Driving Simulator with SCANeR support. You can perform virtual script testing by directly connecting to the VRXPERIENCE Headlamp, ANSYS VRXPERIENCE Sensors, and ANSYS VRXPERIENCE HMI packages. VREXPERIENCE Driving Simulator with SCANeR support reduces the volume of field tests and reduces the time to market by testing an autonomous driving system in a digital environment, Ansys claims.

Ansys 2019 R1

On January 29, 2019, the official release of ANSYS 2019 R1 became available. This was reported to TAdviser by CADFEM CIS, an elite partner, official distributor and center of competence of Ansys.

The entire Ansys line of multidisciplinary solutions has received updates from ANSYS Mechanical to the ANSYS Additive, Twin Builder and VRXPERIENCE software. Key changes were received by modules for additive production, topological optimization, the creation of digital twins, the design and testing of autonomous vehicles.

According to CADFEM CIS, additional functions were obtained applications for modeling the mechanics of a deformable solid, computational hydrodynamics, electromagnetism, thermal analysis and other types of calculations. The process of meshing was accelerated, material property libraries were supplemented, calculation methods were added, and additional animation and model geometry capabilities appeared. Added links for communication between ANSYS products and third-party systems.

ANSYS Mechanical

With ANSYS Mechanical, you can create simulation templates and quickly use the same settings for different geometric models. The standard Workbench Mechanical tool allows you to work with flat axisymmetric general-view models in which you can specify non-axisymmetric loading for axisymmetric geometry created at the grid level based on planar geometry. The capabilities of integration the Mechanical and Maxwell modules in the Workbench platform allow you to perform a full cycle of vibration acoustic calculations (NVH) to obtain the characteristics of electrical machines in the range of rotation speeds. Topological optimization in ANSYS Mechanical supports steady thermal calculation. There is support for optimization for designs simulated in shell staging.

The Solution Combination tool features the following features:

• You can specify multiple combinations.
• You can combine the results of various types of calculations: harmonic, static and transient analysis;
• both the linear combination and the root of the sum of squares (SRSS) are possible;
• You can import and export combination result summary tables in *.CSV file format.

ANSYS Mechanical APDL

Another solution scheme appeared - the semi-implicit method (semi-implication), in which a nonlinear calculation passes from a traditional implicit to an explicit solution method at the point of loss of convergence of the solution. The semi-explicit method is useful in problems where the implicit solution method cannot achieve convergence due to very high nonlinearity. Using an explicit method to obtain a solution to a highly nonlinear problem over a short period of time significantly increases the reliability of an implicit solution, noted CADFEM CIS.

The REINF264 and REINF265 reinforcement elements in the present version can be used in thermal calculations. Thermal elements SOLID278 and SOLID279 are used as basic elements for them. This opportunity will be useful in modeling complex systems with a large number of elements for which heat load is crucial (for example, chips and printed circuit boards), as well as in calculating automobile tires, tasks industrial constructions and biomechanics, the company believes.

The distributed ANSYS Mechanical APDL solver has received support for processing a single contact pair by multiple processor cores. Models with a large number of contact pairs and/or with large area contact areas do not result in a loss of solver performance due to disruption of load balance between cores.

ANSYS Fluent

As told in CADFEM CIS, there were wide opportunities in the mode of creating a mesh (Fluent Meshing). The following improvements have been made to the typical Watertight geometry workflow process:

• The Add Local Sizing step includes options for specifying body sizes and local settings for automatic curvature and proximity grinding.
• For imported geometry, which is a multi-body assembly that does not have a shared topology setting, a Share Topology step is available to find and close gaps between bodies, and to merge shared surfaces.
• The Setup Rotational Periodic Boundaries step is available, allowing the mesh to match on selected surfaces of cyclic symmetry.

The ANSYS Fluent user interface allows you to use expressions (similar to ANSYS CFX Expression Language) that can specify time-dependent boundary conditions and sources, iteration numbers, coordinates, and variables without using UDF or profiles. The transient solver adds a time step adaptation based on the Courant number. ANSYS Fluent can change the time step during a flow physics solution. This ensures that the Courant-Friedrichs-Levy (CFL) number requirement is met. Time step adaptation based on CFL can be used with both first and second order time sampling schemes.

When modeling Fluent combustion, you can create FGM (Flamelet-generated Manifold) tables based on CHEMKIN flumes in physical space directly in Fluent. This function improves the accuracy of calculation using FGM tables by using a calculated profile of the speed of scalar dissipation instead of assuming the appearance of this profile, according to CADFEM CIS.

ANSYS Icepak

In the Icepak model, Electronics Desktop added two-way electromagnetic loss transmission for communication with HFSS 3D, Q3D, and Maxwell models. There are ready-made datasets for modeling temperature-dependent boundary conditions. In mobile coordinate systems, support for PCB objects (printed circuit board) has appeared.

ANSYS HFSS

Improvements were added to hybrid methods of the Hybrid FEM-IE solution: the ability to take into account the shading of the aperture by the irradiator in HFSS SBR +, adjustable passing/reflecting boundary conditions for HFSS SBR +.

You can model ECAD + MCAD assemblies and support PML boundary conditions for HFSS 3D Layout.

ANSYS Maxwell

To model electrical machines, you have imported CAD and/or loaded an existing Maxwell project into RMxprt to automatically create full 2D and 3D models for transient calculation. Added the ability to visualize complete two-dimensional and three-dimensional fields when solving the problem taking into account symmetry.

In the process of meshing, ANSYS Maxwell adds the ability to monitor mesh density, as well as the Cut edge mesh operation in 2D.

ANSYS Twin Builder

In the updated version, Twin Builder can compile, export, and import a cross-platform Windows Linux (and) binary Twin file (*.twin) that can be deployed on supported IIoT platforms such as and. SAP Leonardo IoT This PTC ThingWorx export option for January 2019 is limited to projects that have the following model types: Modelica, FMU, SCADE Links, dynamic ROMs, static and DXROM, State-space ROM (Icepak ROM, Mechanical ROM, etc.)

In the Modelica utility (model libraries), an integrated library appeared - ANSYS Twin Builder Fluid Power Library for modeling hydraulic and pneumatic systems. Several ergonomics enhancements for Modelica Editor have been added, including the ability to display model code in the Model Editor tab. Added an Average IGBT/MOSFET (Transistor) library component. There is support for the latest version of Matlab/Simulink 2018 a/b for joint modeling and export. Lessons on Modelica are also available in the help system, noted in CADFEM CIS.

ANSYS Meshing

In the presented version, a layer-by-layer tetrahedron construction method, previously available as a beta function, appeared as a full-fledged option. You can use this method to mesh additive manufacturing modeling tasks using 3D printing, including parts with fine geometry, holes, and thin walls. The method builds an unstructured tetrahedral grid, ordered in layers, with a given layer thickness, the company specified.

ANSYS Discovery SpaceClaim

The trim options Remove partial segments and Boundary conforming are added to the Basic Infill Lattices process. Remove partial segments trims the extra parts to the accuracy of the entire lattice element.

Boundary conforming creates a triangular grid on the surface of the trimmed structure and connects it to the regular grid inside.

ANSYS Discovery Live

In a real-time simulation software product, topological optimization is available in test mode. As explained in CADFEM CIS, topological optimization in ANSYS Discovery Live is a high-speed, interactive way to create an optimal form of design that is under the influence of a certain load and design restrictions.

The Level-set approach automatically provides smoothed results. It is possible to extract the facet model based on the calculation and export it to STL.

As of January 2019, the distribution version of ANSYS 2019 R1 is available for download on the ANSYS Customer Portal.

2018: Version 19.2

On September 20, 2018, it became known that ANSYS released the Ansys 19.2 version. ANSYS developers expanded and supplemented the capabilities of all software products of the multidisciplinary line.

Following the rapid development of additive manufacturing technologies, digital twin, predictive analytics, development of autonomous vehicles, Ansys, Inc. optimizes software products to ideally meet the needs of modern users. The ANSYS software package is now more than the software. It is a universal design and virtual experimentation tool at any stage of development, which is already used in almost all industries. Each engineering task is unique and requires an individual solution. Therefore, the range of technologies, like the list of ANSYS software products, becomes wider with each release, providing modern engineers with exactly the tools that they need.

This tool enables you to optimize operations and reduce costs with virtual copy technology for your products or hardware. In the presented version, calculations in the field of application of digital twin technology are significantly accelerated.

Important updates have affected the Discovery line, a powerful software package for interactive modeling. ANSYS Discovery AIM improves the mechanisms for meshing according to the parameters of physical models, increases the speed of displaying simulation results, and adds object decomposition capabilities. One of the main improvements in ANSYS Discovery LIVE is additional automation between design and modeling iterations, which became even easier thanks to the addition of parametric studies. You can explore a large number of design options by changing many different geometric or computational parameters. Features such as simplified geometry creation, physics-aware meshing, and advanced visualization capabilities help accelerate the virtual testing process. This will help accelerate important design decisions early in development.

In this version, additions appeared in ANSYS Workbench Additive and ANSYS Additive Print - the most powerful software products available for September 2018 for fast and accurate modeling of additive production processes. During the simulation process, detailed data on the calibration procedure of machines for additive production of metal products was added. In this version, users have the ability to queue several consecutive tasks for automatic execution.

The ANSYS System Purchasing 2.0 engine enables engineers to leverage HPC resources more efficiently and quickly for multidisciplinary calculations and data interpolation.

Improved user capabilities with tools for computational hydrogasodynamics (CFD). The upgraded working process is combined with the patented technology of building a finite element mesh.

Updates in the field of electromagnetic and temperature field modeling extend the possibilities of designing wireless communications, autonomous vehicles and electrification systems.

Other important changes relate to optical modeling, which saves time and money in prototyping, as well as additional capabilities for modeling composite materials and lattice structures.

2016: Ansys 17.0

On January 27, 2016, version 17.0 of the ANSYS software system became available for download. The release includes a large number of changes, both on the technical part and in the licensing policy^[1].

Promo ANSYS 17.0 (2016)

2012: Ansys 14.5

According to November 2012, one of the main innovations for strength calculations in version 14.5 is the tools for analyzing fracture mechanics in the mechanical interface. In the ANSYS Composite PrepPost (ACP) calculation module, you can now prepare each part in an assembly for calculation in a separate ACP (Pre) application and then combine them in a single strength calculation. The mechanical interface itself has been refined. It is also important to change the structure of the results files, which leads to a significant reduction in their size.

In the field of computational hydrodynamics, the main areas of development remained the same: expanding the set of physical models, increasing the stability of numerical methods, deepening the connections of calculation modules for interdisciplinary analysis, as well as integrating all program modules in the Workbench environment.

For ANSYS Fluent, the capabilities of physical models continue to expand. Euler and Lagrangian models of multiphase currents underwent a significant number of changes. Of particular interest is the new model of compressible fluid, which allows for a more accurate distribution of pressure at the initial steps, and also makes the solution more stable during movement and deformation of the mesh.

Speaking about the update of ANSYS CFX, first of all, it is worth talking about improvements regarding new approaches to the calculation of the flow part of turbomachines, called Transient Blade Row methods. Among other improvements are the refinement of the grid motion algorithms, the boiling model developed at the Rensselaer Polytechnic Institute (RPI), as well as the ability to write data on the trajectories of particles of the Lagrangian phase into a separate.csv file.

The most important and long-awaited innovation in ANSYS ICEM CFD is its integration into the Workbench environment with the ability to control using input parameters.

In the field of high frequency calculations, changes for the better affected the package for electromagnetic modeling of HFSS. For example, hybrid technology, combining FEM (finite element method) and MoM (moment method) solutions, will now allow analyzing devices interconnected by a conductor, which in turn will allow developers of microwave devices to be more realistic in solving problems. The full integration of HFSS with Mechanical (Steady-State Thermal) and Mechanical (Static structural) is displayed.

Next, let's say a few words about programs for modeling a low-frequency field and complex analysis of electrical systems. As you know, ANSYS Maxwell 2D/3D, including RMxprt and ANSYS Simplor are integrated into ANSYS Workbench, but are installed in separate packages. In the future update of ANSYS Maxwell v16, ANSYS Simplorer v11 programs, the development team paid great attention to the wishes of customers actively working in this direction. Improvements affected the grid generator for 2D models. The quality of the 2D TAU grid partition by the generator for complex models has improved markedly.

The possibility of bringing three-dimensional transient tasks with minor eddy current effects and with the absence of a constant signal component to a quasi-stationary mode by introducing a new element into the ANSYS Maxwell Circuit has been added. Fixed a number of errors known from the previous version

The main improvements for creating FE grids in Workbench Meshing in version 14.5 include automation of routine operations, improvement of algorithms. To speed up work with large grids, the developers added a display mode for mesh controls without the grid itself. You can now customize filters to display the Model Tree.

Updates to geometric interfaces and CAD applications can DesignModeler include faster and easier use of existing tools. You can note a significant improvement in performance, especially when working with large assemblies, support for formats of new versions of CAD packages. In the new version of ANSYS, it became more convenient to work with Named Selection: new rendering modes appeared, simultaneous work with several Named Selections became possible.

1970s: History of software system development

The first implementation of the program was significantly different from its latest versions and dealt only with solving the problems of heat transfer and strength in linear staging. Like most other programs of that time, she worked in batch mode and only on super-computers.

In the early 70s of the XX century, many changes were made to the system in connection with the introduction of new computing technology and the implementation of user requests. Nonlinearities of various nature were added, it became possible to use the method of subconstructions, the library of finite elements was expanded. The company drew attention to personal computers and vector graphics terminals that appeared at that time. For several years, these new hardware were mastered by the company's software developments.

In the late 70s, an interactive mode of operation was a significant addition to the ANSYS system. This greatly simplified the procedures for creating a CE model and evaluating results (pre- and post-processing). It became possible to use interactive graphics to check the geometry of the model, given material properties and boundary conditions before the start of the account. Graphical information could be displayed immediately for interactive monitoring of solution results.
