SolidWorks SimulationXpress is design analysis software fully integrated with SolidWorks that simulates testing a part prototype under working conditions. It helps evaluate how safe, efficient, and economical a design is. The process involves building a SolidWorks model, manufacturing a prototype, testing it under loads, and modifying the design in SolidWorks until satisfied. Analysis reduces design cycles, costs by simulating tests, and time to market. It uses the finite element method to subdivide a model into simple elements and solve problems too complex for analytical solutions. Common analyses include static stress analysis to calculate displacements, strains, stresses, and reaction forces.
