Published on

This session will cover concepts behind Solid Edge’s simulation capabilities, that which is included in standard Solid Edge along with the advanced features available with Solid Edge Premium. This session is targeted towards designers and/or engineers who need an overview of simulation functionality. Key topics will include simulation options, setting up simulation studies, model preparation, the application of boundary conditions including forces and constraints, meshing, solving, and examining results. Additional topics will include the new features available in Solid Edge ST4. Examples of various component types will be presented and include “thick” parts, sheet metal parts, and assemblies. Anyone interested in learning about Solid Edge’s engineering analysis capabilities should attend this session.
