Elcut

Elcut is a complex of programs for engineering modeling of electromagnetic, thermal and mechanical tasks the finite-element method. The friendly user interface, simplicity of the description even of the most difficult models, ample analytical opportunities of a complex and high extent of automation of all transactions allow the developer to focus on the task completely.

The outstanding scientist Vyacheslav Vyacheslavovich Dombrovsky stood at the origins of the Elcut program (1930-2016).

It is possible to begin work with Elcut practically at once, without being distracted by studying of mathematical bases of computing algorithms and features of their implementation.

Elcut is the full Windows application which was developed especially for this platform and completely uses all opportunities of modern computers.

Components

The Elcut complex contains modules for the solution of different tasks which can be ordered separately. Besides, all versions of the program the editor of geometry, the editor of data, a solver and the post-processor turn on. The type of a solver, the editor of data and the post-processor depends on a type of a solvable task. Also the structure of Elcut includes several superstructures, including LabelMover for the parametrical analysis.

The majority of opportunities of the solution are available also programmatically, from the user programs written in different languages.

Structure of Elcut

Modules:

• Magnetistatics
  • The module magnetistatics can be used for calculation and the analysis of devices such as solenoid, electrical machines, magnetic screens, permanent magnets, magnetic disks, and so forth.

• Magnetic field of sinusoidal currents
  • The module magnetic fields of alternating currents can be used for the analysis of distribution of whirling currents. For the set frequency, he can analyze magnetic fields from alternating currents, whirling currents induced by alternating magnetic fields. Opimalen for design of installations of induction heating, transformers, coils, electrical machines, and many types of inductors.

• Non-stationary magnetic field
  • The module non-stationary magnetic field can be used for calculation of transition processes in electromagnetic devices, operation of engines from pulse converters and other tasks where it is not enough only the solution of a problem of magnetistatics or sinusoidal currents.

• Electrostatics
  • The module an electrostatics can be used for calculation and design of the different systems having capacity such as condensers, transmission lines and so forth and also isolation calculation.

• Electric field of direct currents
  • The module electric field of direct currents can be used for calculation of the different carrying-out systems: grounding conductors, printed circuit boards. And also for calculation of stray currents and leakage currents of insulating constructions.

• Electric field of alternating currents
  • The module electric field of alternating currents is used in the analysis of the electric fields caused by alternating currents and tension in nonideal dielectrics. This analysis type is most often applied when calculating complex systems of isolation and condensers. Usually ohmic losses in dielectrics, tension, components of electric field, force, turning couples are of interest.

• Non-stationary electric field
  • The module non-stationary electric field is used in the analysis of the electric fields caused by the changing currents and tension in nonlinear dielectrics. This analysis type is applied when calculating complex systems of isolation, varistors, limiters of overvoltage. Usually dynamics of process, electric field intensity, forces are of interest.

• Heat transfer
  • The module a heat transfer can be used for design and the analysis of a thermal status of the different systems. It is possible to calculate as the established distribution of temperature, and to study processes of heating and cooling.

• Elastic deformations
  • The module elastic deformations can be used for calculation of mechanical stresses in different devices. It both building constructions, and equipment of high pressure and also separate nodes of mechanical systems.

• Connected tasks
  • Elcut can solve the connected problems when results of calculation of one task are transmitted to other task. For example, heating of a wire due to losses from the proceeding current.

• Electrical circuit
  • Problems of magnetic field of alternating (sinusoidal) currents and non-stationary magnetic field can use an external electrical circuit. It allows to combine field and chain calculations. It is possible to set complex circuits of connection of Elcut blocks. Such setting is convenient for modeling of electrical machines, transformers and other electromagnetic devices.

2018: The choice of C3D Toolkit for development 3D - modeling in Elcut

The Russian developer of the settlement software of Torahs announced on June 14, 2018 that he selected the C3D Toolkit tools for development 3D - modeling from the Elcut program.

The company will use three components from the C3D Toolkit set: geometrical core of C3D Modeler, module of data exchange C3D Converter and module of visualization C3D Vision. They will replace freely extended Open Cascade Technology libraries with which worked Torahs earlier.

The Elcut program executes computational modeling of electromagnetic, thermal and mechanical tasks the finite-element method. Electrical equipment and power industry and also construction physics, heat engineering, geophysics belong to its main scopes.

Remaining the developed program for two-dimensional calculations, Elcut is concentrated on three-dimensional tasks in recent years. Application of the C3D Toolkit components will allow to improve geometry of 3D models to receive the qualitative approved irregular grid of terminal elements and to make the analysis of jumps of a field on borders of physical mediums, consider in the company of Torahs.

Why Elcut developers refused an opensource-core and passed to C3D, Semyon Dubitsky, the director of Torahs explained: "First three-dimensional Elcut was based on an open geometrical core. Dealing with a problem of a mnogotelnost, we understood that the problem of collision of bodies and creation of a surface of contact is insufficiently solved in Open Cascade. Besides, to obtain information on structure and functions of a core outside standard documentation it was extremely difficult, not to mention implementation of new functionality on our requests. Therefore, despite need of acquisition of the commercial license, we made a choice for benefit of C3D core. We were attracted by its sufficient functionality, good documentation, positive approach of C3D Labs developers to requests of new functionality, their instant answers to our addresses".

"Torahs" is going to provide to users of the Elcut program the three-dimensional functionality based on a geometrical core of C3D until the end of 2018.
