Thermal constraints

Thermal constraints are constant temperatures applied to geometry or nodes.

You can define a thermal constraint in three ways:

• The non-spatial Fixed Temperature type lets you use an expression or field to define the temperature magnitude to geometry or FE entities. In addition, you can use the spatial distribution method to define how the boundary condition magnitude is distributed over the model.

• The Node ID Table type lets you use varying temperature values at the nodes identified in the node ID table.

• The Temperature – Spatial type lets you define the temperature magnitude as a spatial field. The spatial-type loads are best for applying externally generated results to the model, since they use a field to define the units for the boundary condition, which corresponds well to external data.

Where do I find it?

Application	Pre/Post
Prerequisite	An active Simulation file with Nastran, Abaqus, or ANSYS as the specified solver and Thermal as the specified Analysis Type
Command Finder	Thermal Constraints
Simulation Navigator	Right-click Constraints→New Constraint→Thermal Constraints
