Model Order Reduction Software for MEMS-based Devices and Sensors

 

 

mor4ansys is a tool to perform model reduction for finite element models developed in ANSYS. The source code for mor4ansys is distributed under the GPL license.

 

The goal of our tool is to employ the recent mathematical model reduction algorithms for the linear finite elements models. In our experience for thermal and structural mechanics problems, the transient and harmonic response of the FE models up to a dimension of 300 000 can be well approximated by a reduced model of a dimension of less than 30.

 

The model reduction time is comparable with the ANSYS stationary solve. As result, model reduction can be used as fast solver for transient and harmonic simulation.
