Simcenter Amesim
System-Level Thermal Management — See the Big Picture
Multi-domain 1D simulation for architects who need to decide cooling strategy, HVAC topology, and battery TMS before CAD or controls exist.
What It Is
Amesim couples thermal, fluid, mechanical, electrical, and control domains in one model. It is the tool that answers the architecture questions — refrigerant vs coolant, pump-driven vs immersion, series vs parallel — before anyone commits to geometry.

Six-stage workflow position
Why engineering teams choose Amesim.
Representative engineering situations these tools are asked to resolve.
- 01
A vehicle programme must choose between refrigerant-based and coolant-based battery thermal management 18 months before CAD exists, and the decision fixes the architecture for the platform. Amesim returns WLTP range and 10–80% fast-charge time for both topologies under the same mission profile, so the trade is settled with numbers rather than precedent.
- 02
A fuel-cell balance-of-plant shows 6 °C stack temperature swings under transient load that no single-domain model reproduces, because the cause is the interaction of coolant inertia, humidifier response, and controller gain. Amesim couples the thermal, fluid, and control domains and identifies the controller time constant driving the oscillation.
- 03
An aircraft environmental control system must hold cabin temperature through a 90-second descent transient, and the controls team needs a plant model for hardware-in-the-loop before any rig exists. Amesim exports a real-time-capable thermal model, so control law validation starts months earlier than the rig schedule allows.
