A contact resistance material type has been applied between two volumes. There does not seem to be a temperature gradient across the resistance. The effect of the increased thermal resistance is not apparent in the temperature results.
- Contact resistances must be placed between solid volumes. If the contact resistance is applied between a fluid and a solid material, it won't work. The best approach for a fluid/solid interface is to apply a solid surface material with insulative properties.
- Check the mesh on the contact resistance surface and ensure it is sufficient to capture thermal gradients.
- Check mesh on neighboring solids to ensure it is sufficient to capture thermal gradients. At least two layers of elements are recommended across heat conducting solids.
- Check the temperature results: Use a temperature XY plot across the two solids across the contact resistance to see if there is a distinct jump in temperature at the interface.
