Thermal Expansion (for Constraints)
Add the Thermal Expansion subnode to a constraint (Fixed Constraint or Prescribed Displacement, or to Fixed Constraint, Interface or Prescribed Displacement, Interface) to prescribe a deformation of the constrained boundary caused by changes in temperature of the surroundings. This makes it possible to reduce the stresses caused by such boundary conditions.
Shell Properties
This section is only present when the parent node has layer selection.
When Use all layers is not selected.
Interface Selection
This section is only present when the parent node has interface selection.
Select the interface or interfaces for which this thermal expansion is to be added.
When Selected Interfaces is selected.
All other settings for the Thermal Expansion node are described in the documentation for Thermal Expansion (for Constraints) in the Solid Mechanics interface.
