Simcenter 3D Thermal
Finite Element Thermal Simulation Tightly Integrated with Structural Analysis
FE-based thermal simulation coupled with structural, acoustic and motion analysis inside NX. The tool of choice when thermal loads drive structural performance.

What It Is
Simcenter 3D Thermal answers the questions where temperature is only the beginning — thermal stress, warpage, creep, fatigue, and life. Native NX integration means geometry updates flow directly into the thermal model, and the same model produces stress and displacement, not just temperature maps.

Six-stage workflow position
Thermal-structural coupling and fatigue are system-level concerns; the aerospace and space use cases sit at system scale.
Why engineering teams choose Simcenter 3D Thermal.
Representative engineering situations these tools are asked to resolve.
- 01
A high-power module warps 40 µm under thermal cycling and loses TIM contact at the corners — Simcenter 3D Thermal resolves the coupled thermal-structural problem in one model, not two.
- 02
A satellite payload must survive orbital thermal cycling with view factors changing every 90 minutes — Simcenter 3D Thermal resolves the radiation-conduction transient and predicts the resulting stress on the bonded interfaces.
- 03
A turbine casing shows creep-driven distortion that a thermal-only model cannot predict — Simcenter 3D Thermal couples transient temperature to the structural creep response in a single environment.

“Coupling thermal and structural analysis in one environment has helped us identify warpage and stress issues that a thermal-only simulation would have missed.”
