A solid material is placed near a heat source whose temperature stays constant. Heat transfer across the gap between the solid surface and the heat source can take place via gap conductance or gap radiation (thus, there are two tests for each element type). Using the default convergence tolerances in ABAQUS/Standard, the reaction fluxes for radiation problems show slight differences (0.1%) from the analytical results due to the severe nonlinearity of the radiation problem. We initiate unidirectional heat flow by applying a constant temperature that is higher than that of the heat source itself to the solid surface away from the heat source. The steady-state temperature at the surface near the heat source is used to verify the numerical solutions.
In ABAQUS/Explicit the steady-state result is obtained by performing a long-term transient simulation. The constant temperature heat source is modeled three different ways: with either deformable elements, isothermal discrete rigid elements, or an isothermal analytical rigid surface. Both kinematic and penalty mechanical contact are considered.
Model: Material:| Conductivity in solid | 1.0 |
| Gap conductance | 10.0 |
| Radiation constants of surfaces | 5 × 10–10 |
| Absolute zero | –460.0 |
In ABAQUS/Explicit dummy mechanical and capacitance properties are specified to complete the material definition.
The steady-state temperatures agree with the analytical, one-dimensional heat transfer results.
