SOLIDWORKS Simulation Video: What's New in SOLIDWORKS 2021 - 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 Terminology Updates for SOLIDWORKS Simulation User interface terms related to contact and mesh are updated to match conventional industry terminology. The term Interaction is introduced to describe the type of behavior between components during a simulation (bonded, contact, or free). Contact Stabilization Contact detection is enhanced with a contact stabilization algorithm that can resolve under-constrained conditions. Contact stabilization acts as a numerical stabilizer by adding a small stiffness to qualified areas before they come into contact. Robust Default Interaction Settings Simulations that have bonded and contact definitions are more robust, even for models with slightly imperfect geometries. Algorithms that detect clearances between geometries and enforce appropriate interactions are improved, and user interface selections are simplified. Improved Bonded Formulation The accuracy of results for static, frequency, and buckling studies is improved for geometries that have bonded interactions. Improved algorithms that mesh bodies independently drive this improvement. Geometry Corrections for Surfaces in Contact Simulations for linear static studies are more accurate for curved surfaces that come into contact. Switch Source and Target Faces for Local Interactions For local interactions, you can switch the geometry selections between the source and target sets to resolve convergence issues. When you are working with complex geometries that have multiple faces, switching the geometry entities between the source and target sets with the Swap interaction faces tool saves you time. Default Mesh Settings The default mesh settings for new studies facilitate mesh assignments for most models. Enhanced Blended Curvature-Based Mesher The Blended Curvature-based mesher has improved performance based on optimized code architecture, multithreading, and parallel multicore processing. The improved mesher can mesh parts and large assemblies significantly faster. Mesh Quality-Diagnostics Tool Improved diagnostic tools help you examine the quality of a mesh and detect poor-quality elements. Simulation Solvers The solution time of linear static studies with many surface-to-suface contact elements is improved. The Intel Direct Sparse solver can handle linear static and nonlinear studies with more than 4 million equations. Improved Post-Processing for Very Large Models The post-processing of stress and strain results is enhanced for models that have more than 10 million elements. Simulation Evaluator The Simulation Evaluator is enhanced to flag study definitions related to the assigned friction coefficient for contacts and materials for invalid Poisson's ratio values. Pin Connector Forces Listing pin connector loads at the pin joints is more accurate for shear forces and bending moments in the global or a user-defined coordinate system. Copy Tabular Simulation Results to Clipboard You can copy tabular simulation results displayed inside PropertyManagers to the clipboard and paste the copied data from the clipboard into a Microsoft® Excel® or Word document. You can copy reaction forces, free body forces, contact/friction forces, connector forces, and probed results. Performance Improvements in SOLIDWORKS Simulation Professional and SOLIDWORKS Simulation Premium Improvements in contact calculations and multicore meshing make simulations faster.
