I am having a problem assigning Internal Fan/Pump material. At first I thought there was a problem assigning a custom Internal Fan material, but I also tried the default fan materials and they did not work either.
I have never had this problem before and it just started happening out of the blue today.
What might be the issue? How can I fix it?
Solved! Go to Solution.
Nevermind, I found the problem. I had assigned two boundary conditions before I had finished assigning all materials. For some reason this was preventing me from assigning the Fan material. When I deleted the BCs, I was able to assign the Fan material with no problem.
