MultiphysicsHow does SIMULIA define multiphysics?Multiphysics is the inclusion of multiple physical representations to capture realworld phenomenaCollection of individual physical phenomenaFull 3D physical “field” modelsStructures, flow, acoustics, EM, microstructures, chemistry, Simplified representation of physical phenomena1D models (heat, flow, circuits, connectors )Logical models for feedback or control mechanismsModes, substructures, matrices, Interaction between various physical phenomenaSequential simulation chains (EM- thermal- structural, submodeling, )Co-simulation (FSI, logical-physical, 1D-3D, multiscale, embedded, HIL )15
