I have to run this thermal analysis for my Senior Design but it is not working. For the second instance the solver stays at Step 9 and the first instance (where the heat sink is included) the solver can't mesh the design. For the second study I tried changing the mesh to curvature mesh and for the first study I tried using mesh controls for the thin extrusion to a finer mesh and suppressing the fillet in teh original design, but none of these work. Could it be that I am not setting up the analysis right? Is it the design itself? Please help.
