Abaqus Release Notes  


6.15 Performing response spectrum analyses using the high-performance SIM architecture

Products: Abaqus/Standard  Abaqus/CAE  

Benefits: A response spectrum analysis can now superpose eigenmodes extracted using the AMS eigensolver or the Lanczos eigensolver with the SIM architecture. This enhancement allows you to analyze large models that involve a large number of eigenmodes for modal superposition.

Description: The SIM architecture now supports response spectrum analyses. You invoke the SIM architecture in eigenfrequency extractions by specifying the AMS eigensolver or by specifying the Lanczos eigensolver based on the SIM architecture. All modal and directional summation methods for response spectrum analysis are available within the SIM architecture.
