Simulation of Parts and Assemblies in a Computer Aided Design Modeling Environment

The disclosed simulation environment, methods, and system support simultaneous design and analysis of assemblies with unified computer aided design (CAD) and finite element analysis (FEA). The system provides a simulation environment that is unified with the architecture of the assembly environment, which significantly reduces the amount of time it takes to set up structural simulations as compared to prior simulation tools. The system enables CAD designers to obtain accurate mechanical guidance such as strength and rigidity early and often in the design process, seeing the structural impact of CAD modifications at the sketch, part, and configuration level. Such guidance can be particularly helpful when CAD engineers are determining product fit and form, defining dimensions, and shaping the overall weight and volume of designs.
