hmtoggle_arrow1Support for DDM (2017)
•Strain Energy and Residual Force Calculations are now parallelized for Static Analysis.
•Fluid-Structure Interaction with OptiStruct-AcuSolve coupling.

 
hmtoggle_arrow1Host Information Printing for MPI Cluster (2017)

Host names on which MPI processes are run on the cluster are now printed to master .out file.

 
hmtoggle_arrow1Speedup for Modal FRF with Enforced Motion (2017)

The computational speed for Modal Frequency Response with Enforced motion using AMSES is improved with PARAM,AMSE4EFM,YES. This is turned off if viscous damping is present in the model.
