Real-world mechanical behavior is often the result of several physical factors acting simultaneously. Multiphysics software allows engineers to simulate a product's behavior when those multiple physical factors interact. User-friendly tools and wizards automate the application of results from one type of analysis to another. The Professional Multiphysics core package includes analysis capabilities for static stress and Mechanical Event Simulation (MES) with linear and nonlinear material models, linear dynamics, steady-state and transient heat transfer, steady and unsteady fluid flow and electrostatics. MES simultaneously replicates the dynamic flexing behavior of a component or mechanism to predict stresses that may result from motion or from the interaction of the part with other independent objects. This core package includes FEMPRO, an easy-to-use, single user interface for finite element modeling, results evaluation and presentation and a suite of modeling capabilities.
