1. Import your 3D CAD model and generate a mesh, or upload pre-meshed files from COMSOL, Ansys, or Gmsh.

2. Define materials, heat sources, and boundary conditions using constant, spatially varying, or temperature-dependent profiles.

3. Use custom mathematical expressions and apply scalar or vector fields.

4. Run steady-state or frequency-domain simulations with one click.

5. Instantly visualize the full 3D thermal distribution, even for complex geometries.
