Multiphysics How does SIMULIA define multiphysics? Multiphysics is the inclusion of multiple physical representations to capture real- world phenomena Collection of individual physical phenomena Full 3D physical “field” models Structures, flow, acoustics, EM, microstructures, chemistry, … Simplified representation of physical phenomena 1D models (heat, flow, circuits, connectors…) Logical models for feedback or control mechanisms Modes, substructures, matrices, … Interaction between various physical phenomena Sequential simulation chains (EM->thermal->structural, submodeling , …) Co-simulation (FSI, logical-physical, 1D-3D, multiscale , embedded, HIL…) 15
