ANSA for model-change according to design variables (everything besides LS-DYNA with *PARAMETER) μeta for results extraction of arbitrary (supported) solvers (besides LS-DYNA) Setup phase design variables defined in ANSA transfer to LS-OPT histories and responses defined in μeta transfer to LS-OPT Optimization (Run) phase design variables controlled by LS-OPT transfer to ANSA histories and responses calculated by μeta transfer to LS-OPT
