Maximum Number of Iterations: CHT

I am new to SimScale and I am trying my first project. I am trying to simulate a convectional dryer that uses water at 180 F as a heat transfer and trying to see the thermal effects of each layer of the dryer. Air is contained on the inside of the chamber as well. So far I have all check marks on the tree but when I run the simulation I receive the “Max # of Iterations” flag. I’m not quite sure what to do at this point.

Give me some time to investigate this @dnlrosenfeld! Also tagging our experts, the @cfd_squad here in case someone wants to jump in.

Your mesh is not very fine compared to the small thickness of the layers and this could be causing the problem. You will need a very fine mesh for this simulation and will need to use mesh refinements to increase the mesh fineness of the screw. I am not entirely sure how the device you are simulating operates, but if you can reasonably avoid meshing the screw then do so, it will save you a big head ache!
