Forgot to mention, the heat load is applied to a split surface on the box. The width of the heat load surface is only 0.0053 mm in width..... very narrow!
I suspect somehow that's too small for the mesh to catch?
I am trying to do static thermal modeling of a box with the following dimensions:
W: 0.400mm
L: 1.500mm
T: 0.0035mm (3.5um)
One side of this box generates heat and flows to a big heat sink below at a fixed temp. The big heat sink is much bigger (100x) than the heat source.
After many...
