•Restart for Nonlinear Analysis: Restart (save results and retrieve for restart) is now available for nonlinear analysis.
•Debugging Utility for Nonlinear Analysis: With new option added as PARAM,NLMON or subcase selector NLMON, the displacement results for each iteration will be available in the _nl.h3d file while the job is running. This is available for both small and large displacement analysis.
•NLMON will also output useful diagnostic data (Max Residual Force and so on) in .out file for Large Displacement Analysis. With TCL script provided in installation, the script will parse the .out file and help the user identify which nodes have convergence issues.
•Finite Sliding with CONSLI now supports smoothing option: SMOOTH option on CONTACT is now supported for Finite Sliding with CONSLI option.
•Both sides of surface results available for Surface-to-Surface Contact: Both Master and Slave side of results are available for surface-to-surface contact.
•DOFs selection for MPC based TIE Contact: The user can now choose DOFs to be constrained for MPC based TIE contact.
•Enhanced Performance with Multiple Processors: Some of the calculation for nonlinear analysis is sped up with OpenMP implementation. The performance benefit would be seen in large displacement analysis or the nonlinear material with plasticity.
•DIRECT option available in NLADAPT: With DIRECT option on NLADAPT, the user can choose fix time step for Large Displacement Analysis instead of dynamic time step schema.
•CELAS in Large Displacement Analysis: CELAS is now supported in Large Displacement Nonlinear Analysis.
•Material Stability Check for Hyper Elasticity: The results of stability check is available in the .out file. Such output can be turned off with PARAM,CHECKMAT,NO.
•PLOAD/PLOAD2 as Follower Forces: PLOAD, PLOAD2 entries are now supported as Follower Forces in Large Displacement Nonlinear Analysis.
