Axisymmetric heat transfer - Thermal contact resistance

Tim_GowingTim_Gowing
Hi Victor,
I wish to create contact resistance between adjacent meshes in a purely theremal axisymmetric analysis. I don't see this contact option for the internal solver, is that correct?
I've posted a Calculix forum question also as no joy with Calculix. I'm not clear on whether contact resistance (*Gap conductance) is possible, 2D, edge to edge, CAX4 elements; have you ever tried this?
Kind regards,
Tim

    Correct, the internal solver doesn't support thermal contact conductance.

    I don't see any reason it wouldn't be possible with axisymmetric elements in CCX. It's just that Mecway that doesn't have them. You could do what CCX does internally and revolve a 2D mesh into a single element thick wedge. Then you get all the capabilities of 3D, including thermal contact conductance (*GAP CONDUCTANCE).

    Thank you Victor, I'll try the revolved wedge.
