Heat Transfer

Solve conduction-dominant heat transfer problems with convection and radiation occurring at boundaries

Note

Domain-specific heat transfer workflow is not recommended. New features might not be compatible with the this workflow. For help migrating your existing code to the unified finite element workflow, see Migration from Domain-Specific to Unified Workflow.

In this workflow, you can only specify and store parameters belonging to thermal analysis. To store all physical parameters for structural, thermal, and electromagnetic analyses, and for ease of switching between analyses types, use Unified Modeling. For help migrating your existing code to the unified finite element workflow, see Migration from Domain-Specific to Unified Workflow.
