Simulation Express provides a basic, quick way to run stress tests on single‑body parts in SOLIDWORKS without a full Simulation licence. It supports simple fixtures, forces, pressures, mesh control and basic results such as stress, displacement and factor of safety. The webinar explains what simulation can and cannot do, highlights common pitfalls like incorrect restraints or load applications, and demonstrates better practices using roller sliders, bearing loads, virtual walls and foundation bolts. It also covers meshing methods, including mixed element types and shell modelling, and ends with guidance on key settings and how to interpret common warnings and errors
