SOLIDWORKS Simulation SOLIDWORKS® Simulation Standard, SOLIDWORKS Simulation Professional, and SOLIDWORKS Simulation Premium are separately purchased products that you can use with SOLIDWORKS Standard, SOLIDWORKS Professional, and SOLIDWORKS Premium. Contents Automatic Saving of a Model File You can save a model file after meshing and after the analysis completes. Bonding Interactions for Shells The enforcement of bonding interactions between sets of shell elements that have a physical gap is more robust. Convergence Check Plot The Convergence Check Plot detects regions of the model where the solver has encountered contact convergence issues. Decoupling Mixed Free Body Modes An algorithm can detect and decouple the mixed free body modes while calculating mode shapes. Direct Sparse Solver Retired The Direct Sparse solver is removed from the list of solvers for simulation studies. Enhanced Bearing Connectors The introduction of Distributed coupling and Tilt stiffness enhances the formulation of bearing connectors. Excluding Mesh and Results When Copying a Study You can save time by excluding mesh and results data when copying a simulation study to a new study. Exporting Mode Shape Data You can export mode shape data to the study's study_name.out file. Mesh Performance Performance Enhancements Several feature enhancements improve the performance and accuracy of simulation studies. Underconstrained Bodies Detection There are several usability enhancements for the Underconstrained Bodies PropertyManager.
