I just wanted to put this here. I’m doing a project in the FEM course and I’m done with part one now.

It’s supposed to be a plastic mold injection tool. That means it’s supposed to simulate a situation where there is hot melted plastic on the “inside” of the tool, the right side and the upper part is kept at a constant temperature of 25 degrees Celsius somehow and the other sides of the tool are exposed to the air so their cooled through convection. The bottom of the tool has no heat-flow at all because it’s supposed to simulate a symmetry, so imagine there is an identical but vertically flipped part on the bottom.

Anyway, here is the simulation of the heat dispersion for the first 5 minutes after the plastic is injected into the tool.
