Thermal contact resistance

Tim_GowingTim_Gowing

I have a model with several metal and insulating parts, and I am interested in the heat flux through the assembly.

I have created the model using bonded contact and I have run it using both the Mecway and Calculix solvers, both results ok.

Now I wish to include the contact resistance between the components, is this possible directly from within Mecway?

My plan for a workaround is to write out a mechanical deck including CCX contact and then hand edit the deck to convert to a thermal job with *GAP CONDUCTANCE.

I will appreciate any guidance.

    That would pretty much be how to do it currently. Though, writing a mechanical .inp file might lead to a lot of manual changes being needed, so after adding the contact, you can change the analysis type back to thermal so it creates a thermal .inp file with the contact.

    Victor,

    Thank you confirming the route for gap conductance.

    What are your plans for enhancement of contact definitions in the next Mecway versions?

    I've added gap conductance to my list. Version 6 is nearly up to beta so probably no new features for that though. But it will have many of the common CCX pain points improved on.

    Thank you Victor,

    Looking forward to using V6
