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

11

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…)
