2021
Criminal Police Service LP "PolygonSoft" 2021.0
CSoft Development on October 27, 2021 released an updated version of the engineering analysis system for foundry processes Criminal Police Service of the PolygonSoft LP 2021.0.
Version 2021.0 is released just eight months after the previous release. PolygonSoft has passed the testing stage, and its distribution to users on technical support will begin in September. Such a quick release of the updated version is primarily associated with the implementation of developments that began back in 2020 and the desire to satisfy the needs of users.
The updated architecture of the PolygonSoft LP Criminal Police Service continues to replace the old code, and the modules that have lost their relevance are replaced with new ones, or deleted. All old solvers are excluded from this version, as well as the model preparation module for calculating the radiation heat exchange "Tracing." All of them are completely replaced by other, more accurate and faster, solvers, which were gradually implemented over the course of several previous releases.
Starting from version 2021.0, work begins on replacing the editors of the Alloy module with more current and functional ones. At the request of users, the modernization began with the two most used ones - the heat transfer parameter editor and the set temperature editor. The [data] they generate is part of the concept of a "process plan template."
In Criminal Police Service LP "PolygonSoft" 2021.0, users will find an updated version of the Euler current solver with faster and more stable algorithms and an updated Fourier solver. Both solvers underwent deep code refactoring, which is primarily associated with the transition to a different data model, as well as the introduction of an approach according to which calculation is considered as a project to create technology. As a result of the changes, users will be able to use variable heat transfer parameters between bodies and the environment, assign more flexible temperature conditions. Switching to "end-to-end" process time allows you to use the same settings for all solvers without having to replace the boundary conditions when changing the solver. In particular, it has become possible to model melted refrigerators already at the stage of filling the mold.
When casting in vacuum, the effects of reflection and absorption of energy by bodies must be properly taken into account. The updated Routing module is enabled by the Radiation Heat Exchange option and automatically prepares the geometry for calculation. In this version, the developers were able to once again significantly improve data processing, which is especially noticeable on large models.
An elastic-plastic model of the behavior of the shape during contact with the casting has been added to the Hook solver. At the same time, a model for predicting hot cracks during shaped casting was added. Previously, the probability of their formation was estimated by plastic deformations, which generally corresponds to reality, but recently situations have begun to arise when this method was not enough. Focusing on the wishes of users, the developers have created a special model that calculates the tendency to hot cracks based on an analysis of the level of plastic deformations and the nature of solidification of the casting.
The tool for checking and automatically improving the quality of the stack, developed and implemented in the previous version, has been significantly redesigned and improved. Added validation criteria - along the length of the edge of the element - too small elements are removed and replaced with larger ones.
Other important updates include the ability to restore and continue the interrupted calculation, fix and improve the functionality of the "Master" and "Mirage" modules.
Criminal Police Service LP "PolygonSoft" 2020.0
CSoft Development on February 10, 2021 presented the next version of Criminal Police Service "PolygonSoft" 2020.0
The updated system architecture continues to replace the old code, and modules that have become irrelevant are replaced or deleted. The system passed all the main stages of testing at the end of 2020 and is available to users for February 2021.
The updates affected both user interfaces and mathematical models.
- An additional tool has been implemented in the grid generator.
- The Master preprocessor now remembers the last task the technologist was working on and offers to import all settings into the new grid model of the foundry.
- A modified "Master of building ceramic forms and thermal insulation shells" appeared.
- The version of the Euler current solver has been updated.
- The Save Calculation Time option will help you optimize the dimensions of the calculated area.
- Pause before stopping the flow calculation will be very useful in modeling the casting of large ingots.
- The Routing module is enabled by the Radiation Heat Exchange option and automatically prepares the geometry for calculation.
- In Criminal Police Service LP PolygonSoft, support for direct calculation methods in the Fourier solver has been discontinued.
- The Optima module, which was used to prepare the model for calculation by direct method, was excluded from the PolygonSoft LP Criminal Police Service.
- The Slide module is outdated and excluded from the PolygonSoft LP Criminal Police Service.
Other important changes include the ability to calculate stresses in the mold in the Guk solver, an updated model of porosity and radiation heat exchange in the Fourier solver, and other post-processor capabilities.
2020: Criminal Police Service LP "PolygonSoft" 2019.5
On June 9, 2020, SiSoft announced the release by the developer, CSoft Development, of an update to the version of the engineering analysis system for foundry processes released at the end of 2019 Criminal Police Services of the PolygonSoft LP 2019.5. In version 2019. x changes affected almost all modules of the system - from mathematical models to user interfaces. This update offers users additional preprocessor tools and functions, as well as improved calculation algorithms. Changes that have occurred in the licensing system open up the possibility of updating previous versions.
According to the developer, the architecture of Criminal Police Service LP "PolygonSoft" 2019. x smoothly displaces the traditional modular approach to modeling casting technology. The Master preprocessor took over the functions of fully preparing the casting block model for calculation and starting the solution of the problems of filling the mold, hardening, porosity and stress. End-to-end modeling of all stages of the technological process is implemented with automatic switching of mathematical models. For this, all three solvers of the PolygonSoft Criminal Police Service LP were redesigned. This especially affected the current solver, which was actually created from scratch. The updated melt flow model allows you to evaluate the filling process at a completely different, higher stage. The user sets the level of detail of the calculation and selects a balance between speed and rendering quality.
In the updated version of Criminal Police Service LP "PolygonSoft" 2019.5, users will find an Euler flow solver with faster, stable algorithms and an updated heat transfer model at the casting-form boundary. In the preprocessor, the Melt Supply tool appeared for flexible and convenient assignment of mold filling conditions with the possibility of topping up to different elements of the gate-feeding system.
The developer also noted the changes that affected the shell generation algorithm, which is usually used to create a ceramic mold model for casting on melted models. In Criminal Police Service LP "PolygonSoft" 2019.5, another version of the grid generator is used with implemented functions for correcting "bad elements," which allows you to reduce or completely exclude their appearance.
Starting from the presented version of Criminal Police Service LP "PolygonSoft," there have been changes in the licensing policy. All system configurations will be multi-core and have the xCore prefix in the name. This means that all cores of the processor installed on the PC will be available for calculation. At the same time, the licensing of algorithms for generating the properties of casting alloys in the Alloy module was canceled. Thus, users updating their single-core, dual-core, etc. configurations of Criminal Police Service LP "PolygonSoft" will receive instead a multi-core version and a license for the "Alloy" module without additional surcharges.
2015: PolygonSoft 15.0 released
On June 16, 2015, CSoft published a version of the engineering analysis system for foundry technologies PolygonSoft 15.0[1]
It has expanded the functionality of some modules, updated algorithms, replenished databases of casting materials and shapes.

In the main solver of the PolygonSoft system - the Fourier-3D module, the macro and microporosity model has been improved for use with the centrifugal casting option and an arbitrary axis of rotation.
The most serious changes were made in the module for calculating the stress state of the Guk-3D casting. In this version of the solver, a "stabilized" version of the Newton method was created, which allows you to more accurately process the contact of the casting with the mold. At the same time, the developers significantly reduced the calculation time by including an algorithm that helps reduce the number of iterations of the Newton method in the first steps of the calculation. The possibility of calculating the VAT after removing the form (knocking out, disassembling the coke) and removing the elements of the gate-feeding system has been added.
An updated Mirage-3D post-processor with a model tree that controls the visualization of casting and mold elements significantly improves the effectiveness of the analysis of results.
Maxim Tikhomirov, head of the development team, director of SiSoft Polygon Plus LLC, noted: "The new version of PolygonSoft is our next contribution to the development of engineering analysis of foundry processes at domestic enterprises. Each time, starting work on a new version, we carefully consider the strategy for the further development of the PolygonSoft system, select the most popular directions in modeling foundry processes. In 2014, there were many calls to technical support specialists related to modeling the stress state of the casting. Cold and hot cracks are a very common defect, and we have made efforts to prevent it, significantly expanding the functionality of the Guk-3D module. We did not forget about other modules of the system. For example, new functionality has been added to such processor, post-processor and preprocessor modules as Fourier-3D, Master-3D and Mirage-3D. These new functions allow in a new capacity to specifically solve such problems as, for example, calculations for centrifugal casting, casting when using exothermic mixtures, and more effectively control the visualization and preparation of calculations using the so-called model tree. The material database has been expanded. In addition, PolygonSoftware, starting from version 15.0, includes a generator of finite element grids based on freely distributed libraries and modules of the SALOME system. All this and much more was done at the request and suggestions of our domestic and foreign partners and users. I hope technologists will appreciate our efforts. "
2014: PolygonSoft 14.0
On June 18, 2014, CSoft announced the release of a new version of the solution for the development and analysis of metal casting technologies.
The changes affected all modules of the system:
- updated interfaces,
- added new algorithms and models,
- increased performance of some modules,
- The material database has been expanded.
The module for preparing the geometric model "Master-3D" received, among other things, the ability to read finite element models built in the generator CAD system, and NX more flexible algorithms for analyzing and improving the quality of the grid.
Significant changes in all computers of the system. The main module - the Fourier-3D processor - introduced a new model of centrifugal casting with an arbitrary axis of rotation. The module algorithms have been modified to simulate the operation of exothermic inserts. The new shrinkage shell and macroporosity model implemented in the previous version has been redesigned, refined and supplemented with a new microporosity model.
Thermal fields in casting using exothermic mix plate (left) and rod mix (right)
In the new version of the module for calculating the stress state of the Guk-3D casting, an algorithm for the contact interaction of the casting with the mold is implemented. This makes it possible to take into account the difficult shrinkage when analyzing the stress-strain state of the casting. The shape is taken into account in the calculation as an absolutely rigid body.
A complete list of changes in the Criminal Police Service LP "PolygonSoft" 14.0 is available on the vendor's website.
2013: Version 13.4
This version implements a number of ideas aimed at improving and simplifying the modeling of the continuous casting process. A new Hook-3D module has been added to calculate stresses and strains in the casting.
The changes affected almost all modules of the system: the interfaces were updated, new algorithms and models were added, the performance of some modules was increased, the materials database was expanded.
The module for preparing the geometric model "Master-3D" has undergone significant changes, which received in the new version, among other things, a convenient model tree and an improved file loading interface with the ability to read finite element models built in the CATIA V5 CAD system generator.
Significant changes have occurred in all three solvers of the system. So, the Euler-3D module now has a 64-bit version, which is automatically used in MS Windows x64. The solver implements new interface functions that allow you to run source data editors and a post-processor with calculation results directly from the module shell.
The main module of the system - the Fourier-3D processor - introduced a new model of shrinkage shell formation and macroporosity, based on an improved method for step-by-step determination of the shape of the shrinkage shell, taking into account the capillary effect and pressure drop during crystallization of thermal nodes. The new model has been added for use in test mode and can be launched instead of the traditional MACRO model.
