For more information take a look the Short Description.
Further details can be found in the comprehensive Product Description.

The most important extension of VisPER:
Next generation MLDR Solver   
  • Next generation model order reduction.
  • Significant reduction of runtime and disk space.
  • New features compatible with MLDR are Optimization, CONTLOCK and more.
Extensions to the Harmonic Balance Method
  • Huge performance improvements.
  • Available also for fluid-structure coupling.
  • Addmodes are considered.
  • Modal damping.
  • Efficient handling of nonlinear degrees of freedom.
Aligned Rigid Body Modes
  • Rigid body modes are now aligned along global coordinate axes.
  • User-friendly output, no influence on computation results.

New Subspace Iteration Eigensolver
  • Performance improvements in many cases.
  • Improved stability and completeness of eigenpairs.
  • Essential contribution to new MLDR solver.
  • Used in vibration- and buckling analysis.
  • Results of previous task step may be used as starting vectors in buckling analysis.
  • Eigenvectors of coupled fluid analysis may be stored for subsequent runs.
  • Rigid body modes without mass are now handled automatically.
  • Simplifies software maintenance and future developments.
Stress based topology optimization
  • Aggregated global stress constraints greatly reduces computational effort.
  • Suited for very large problems due to global stress constraint.
New Contact Algorithm CAMG
  • Performance boost for contact problems.
  • Improved stability.
Integrated Fatigue Analysis   
  • Stress based high cycle fatigue analysis in time domain.
  • Multi-axial stresses on structural surfaces.
  • Compute damage values for solid elements and schell elements.
  • Provide additional results for verification.
  • Full integration in PERMAS guaranees excellent performance.
New Simulation Workflow using MeshWorks® Pre/Postprocessor   
  • Import CAD geometry or PERMAS DAT file.
  • Automatic FE meshing by functional modules and templates.
  • Optimal mesh quality by assistance tools.
  • Automatic surface pairing detection and creation for contact pairs.
CAD Integration of Topology-Optimization in PERMAS/VisPER   
  • Starts with the CAD-geometry of the design space created in a CAD-System.
  • Delivers a CAD-geometry of the optimized part design.
  • Is completely integrated in the graphical user interface VisPER.
