Problem descriptionModel:The two-dimensional geometry is shown above. Three-dimensional elements are tested with a thickness of 1.0 in the z-direction. In Abaqus/Standard a steady-state simulation is performed, while in Abaqus/Explicit a transient simulation is performed. The total simulation time in the latter case is 20000 seconds, which provides enough time for the transient solution to reach steady-state conditions in this problem. Material:Conductivity = 52 W/m°C, surface convective coefficient = 750 W/m2/°C. For coupled temperature-displacement elements dummy mechanical properties are used to complete the material definition. Boundary conditions:Temperature = 100°C along edge AB. Zero heat flux along edge DA. Convection to ambient temperature of 0°C along edges BC and CD. Loading:Zero internal heat generation. Reference solutionThis is a test recommended by the National Agency for Finite Element Methods and Standards (U.K.): Test T4 from NAFEMS publication TNSB, Rev. 3, “The Standard NAFEMS Benchmarks,” October 1990. Target solution: Temperature of 18.3°C at point E. Results and discussionThe results for the Abaqus/Standard analysis are shown in the following table. The values enclosed in parentheses are percentage differences with respect to the reference solution.
The results for the Abaqus/Explicit analysis are shown in the following table. The values enclosed in parentheses are percentage differences with respect to the reference solution.
