The curing reaction is exothermic. The Curing Reaction Heating multiphysics coupling () adds the source term (SI unit: W/m3) to account for reaction heating in the heat equation:

The Label is the default multiphysics coupling feature name.

The Name is used primarily as a scope prefix for variables defined by the coupling node. Refer to such variables in expressions using the pattern <name>.<variable_name>. In order to distinguish between variables belonging to different coupling nodes or physics interfaces, the name string must be unique. Only letters, numbers, and underscores (_) are permitted in the Name field. The first character must be a letter. The default Name is crh1.

When nodes are added from the context menu, you can select All domains (the default) or select Manual from the Selection list to choose specific domains.

This section controls which individual interfaces are coupled by the current coupling feature. If a physics interface is deleted and then added to the model again, then in order to reestablish the coupling, you need to choose the correct physics interface again from the Curing Reaction or Heat Transfer interfaces lists.
