Simplorer-Fluent Cosimulation

• Typical Application: Battery Cooling

• Design Flow:

• Fluent User

– Creates Fluent design

– Creates Boundary Conditions (defining Parameters) for

cosimulation interface

• Simplorer User

– Uses UI to connect to Fluent design: Schematic component and

Pins are created automatically

– Wires up the rest of the schematic

– Sets up the Transient Analysis and Simulates

• Cosimulation is OS independent

• Cosimulation may use local machine or run over the network

• Simulation results available in both Simplorer and Fluent

Transient co-simulation for non-linear CFD models

© 2010 ANSYS, Inc. All rights reserved. 37

Cosimulation Example: Battery Cooling

• Single battery cell

• Inputs: Inlet Flow Rate (Kg/s) and Heat Source(W/m3)

• Output: Outlet Temperature (K)
