Simulation Automation & Optimization
Process flows with Components:
Execute multiple simulation studies automatically
Distribute across compute resources with Fiper
Evaluate multiple design options
Meet Quality Targets
Design-to-target for attributes
Handle variations (materials, loads, tolerances,
and operating conditions, etc)
Find the Best Design
Which parameters drive targets?
Trade-off design alternatives in real time

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…)
