Isight and STAR-CCM+

Problem: manual iterations too time- consuming and final design may be non-optimal Approach: CATIA for parametric geometry, STAR-CCM+ for pressure drop simulation, Isight for process integration and optimization STAR-CCM+ component generates a macro to update inputs, initialize and run solution and extract outputs Result: Pressure reduced by 11% from initial design

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…)
