MOR inside ANSYS

The simulation of components as 3D-FEM models is well established in the modern development process. Among other things, these models are used in engineering at the system level. Presently, the simultaneous simulations, using multiple solution codes for various engineering disciplines, are integrated into a single dynamic analysis.

MOR inside ANSYS

CADFEM ANSYS Extension for system analysis of 3D-FEM models

One hurdle in this process is the level of detail of the 3D-FEM models, which is often extremely high, and the large amount of data that results. This massive data severely impedes the ability to have a common geometry for different simulations. Model Reduction inside ANSYS (previously MOR for ANSYS, where MOR stands for Model Order Reduction) supports development engineers in their efforts to solve this bottleneck.

As quickly as possible

The algorithms contained in Model Reduction inside ANSYS systematically translate the high-dimensional 3D-FEM model into a size-optimized model with equivalent characteristics. The degree of simplification is prescribed by the user on the basis of an acceptable approximation error. Model Reduction inside ANSYS can be used for any model from ANSYS Mechanical, especially for the piezoelectric and thermomechanical models.

The process of model simplification with Model Reduction inside ANSYS is much faster than a dynamic simulation using the original data. This means that CADFEM ANSYS Extension is suited to be a quick solver of transient and harmonic simulations. The reduced matrix system can be read directly into commonly-used tools for system simulation such as ANSYS Simplorer and MATLAB /Simulink. The simplified model can also be written in the VHDL-AMS or Spice languages.
