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. Video: What's New in SOLIDWORKS 2023 - SOLIDWORKS Simulation Contents Bonding Interactions An improved surface-to-surface bonding algorithm enforces bonding interactions for faces that are not facing each other and have no projection area between them. Diagnostic Tools You can access the diagnostic tools available for simulations from the CommandManager. Linkage Rod Connector The application of Linkage Rod connectors is extended to nonlinear static and nonlinear dynamic studies. Penalty Stiffness Control for Contact You can specify a scale factor for the penalty stiffness for contact that is used in linear static studies. Simulation Solvers Function-based processing for the FFEPlus iterative solver is extended to frequency and buckling studies, and to the linear static studies that include node-to-surface interactions and virtual wall definitions. SOLIDWORKS Simulation Knowledge Base (2023 SP1) The SOLIDWORKS Simulation Knowledge Base articles have migrated from the SOLIDWORKS Knowledge Base portal to the Dassault Systèmes Knowledge Base portal. Underconstrained Bodies In SOLIDWORKS Simulation Professional and SOLIDWORKS Simulation Premium, for static studies only, the Underconstrained Bodies algorithm includes contact interactions and bolt connectors when detecting rigid (or free) body modes of components.
