Problem description
The tests in this section are set up as cases of uniform one-dimensional heat flux using generalized plane strain (Abaqus/Standard only), and three-dimensional elements. In all Abaqus/Standard cases a steady-state heat transfer analysis is performed. In Abaqus/Explicit a transient analysis is performed for each case, with a simulation time chosen to ensure that steady-state conditions are reached in this problem. Particular values (gap clearance, predefined field variables, etc.) vary during the solution, which in turn influence the conductivity across the interface and, thus, the solution.
Results and discussion
The results match the exact solutions.
