Hi everyone,
I'm very new to Comsol. I'm trying to model a resistor with power running through a nichrome section, generating heat. Part of my geometry was extremely thin so I created a free triangular face and then swept through the entire geometry multiple times which worked fine. However, I want to see the effects of conduction with air (however small) as the next step. I'm assuming that air goes to infinity.
I saw that it was recommended to simply put a block around it that was 'big enough'. However when I tried meshing it using free tetrahedral I got the error: "Boundary mesh must consist of triangular elements only." My geometry is too complex to create more swept features and it would be really nice if I could simply use free tetrahedral for the block of air every time I change a dimension of the resistor. Is there any way of getting around this?
Thanks!
Mate M.
