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

APR FSI Fuel pump. WARNING: Direct Injection FSI fueling systems run at very high pressures. The pressure in the fuel lines must be relieved prior to removal of the fuel pump to prevent serious bodily injury. Please consult a factory-approved repair manual (i.e. Bentley manual) for the proper procedures and precautions.
