Scalable reduction of complex 3D FEM models with Model Reduction inside Ansys

Model Reduction inside Ansys – model reduction for faster calculations

The high level of detail of highly dimensioned FEM models is important for the accuracy of the components, for an efficient dynamic simulation and system simulation. Model reduction is the state of the art. With Model Reduction inside Ansys, the number of degrees of freedom (DoF) can be reduced so much that a multiphysics system simulation becomes possible.

  • Fast solverCoupling of reduced-order models at system level

    Practical example of model order reduction (MOR): creating a library of reduced-order models and then coupling those models at system level

  • Voith turbine rotorShortening development time through model reduction
  • SimplificationThe idea of model order reduction – Model Reduction inside Ansys
  • Highly versatileThermal model reduction for electrothermal simulation

    MOR inside Ansys is an efficient tool for automatically generating an accurate, compact thermal model for power electronics. 

Highlights at a glance

  • Krylov-based model order reduction for Ansys
  • Making large models manageable: reduction of a model with 1 million degrees of freedom (DoF) to a compact model with a size of 100 degrees of freedom
  • Significantly faster assessment of transient and harmonic simulations
  • Use of the reduced-order model in system simulations, e.g. Ansys Twin Builder or MATLAB/Simulink
  • Transfer of the simplified model into the VHDL-AMS or Spice languages
  • Transfer of linear models from Ansys Mechanical into Model Reduction inside Ansys, especially for thermomechanical, thermoelectric or piezoelectric models.

Product Description

Model Reduction inside Ansys in Detail

Model Reduction inside Ansys – Software solution for model simplification in partial and system simulations

Model simplification via Model Reduction inside Ansys is suitable for optimization strategies in component development as well as for integrating compact models into an overall system simulation in the fields of electronics, automotive or microsystems. Despite reduction, the examination parameters are retained, which means fast results can be achieved with regards to designs and system simulations.  

Highlights at a glance
  • Powerful Krylov algorithms for significant reduction of data points 
  • Applicable for all linear applications and problems that can be solved using Ansys Mechanical
  • Reduction while retaining dynamic properties
  • Acceleration of model reduction by using system matrices
  • Parametric model order reduction with change of boundary conditions
