Using Thermal Contact in Workbench Mechanical 15.0 – Five Tests Results can be better if the Contact side in a contact pair is on the body with the lower thermal conductivity, and with a finer mesh.

In the present set of tests, apparently best results can be seen if the Details for the contact pair have “Detection Method” set to the non-default value of “Nodal–Projected Normal from Contact”.

Thermal results are affected by settings for the contact pair between the two blocks. A convective load is placed on the right end at a thermal conductor, with convection coefficient h=50W/m2 and an ambient temperature of 22C. In Figure 1 above, a temperature boundary condition of 200C is applied to the left end of the model at a thermal insulator in a two-block model. One block is a thermal insulator, and the other is a thermal conductor. Low-order quad-shaped 2D thermal elements were employed. Imperfection in thermal contact behavior can be inspected in plots of thermal flux in directions perpendicular to the contact elements.Ī series of tests were done on contact between two 2D blocks in contact. This document considers some effects of contact pair settings on thermal results. Manual tweaking of contact pair details can improve contact element performance, and the accuracy of results.
