SOLIDWORKS Simulation SOLIDWORKS® Simulation Standard, SOLIDWORKS Simulation Professional, and SOLIDWORKS Simulation Premium are separately purchased products. Contents Automatic Detection of Underconstrained Bodies You can detect rigid body modes at the early stage of a linear static study's solution. Bonding Interactions with Offset The enforcement of node-to-surface bonding interactions between geometries within a user-defined gap is improved. Contact Penalty Stiffness for Shells A new algorithm is introduced to apply penalty stiffness for contact interactions of shells. This enhancement improves performance and accuracy for a large range of shell thickness ratios. Contact Penalty Stiffness Control for Nonlinear Studies You can adjust a scale factor for the penalty stiffness applied to surface-to-surface contact interactions when solving nonlinear studies. Edge Weld Connector Several enhancements for the Edge Weld connector improve its usability. Enhanced Pin Connector The introduction of a distributed coupling algorithm enhances the performance of studies that use pin connectors. Exclude Bodies from Analysis You can exclude multiple bodies from an analysis. General Spring Connector You can specify a general spring connector between flat, nonflat, and concentric cylindrical surfaces. Geometry Correction for Surface-to-Surface Bonding Simulation accuracy is improved for studies with bonded curved surfaces (surface-to-surface bonding formulation) when the mesh sizes of the source and target surfaces differ. Mesh The total meshing time by the Blended curvature-based mesher is reduced for assemblies that have multiple identical parts.
