Hello all...
I am doing CFD simulation for a shell and tube heat exchanger where in tubes have fin profiles same as ceiling fans...
now when I go for mesh;till volume mesh the quality is 0.2 but after doing prism mesh the quality drops down to 0...

And in fluent,till 30 iterations it goes well..but after that it starts showing that "Temperature limited to 1.00000e00 in so many cells in domain 1....


I have read threads on this forum and tried the solutions described here but couldnt resolve the problem...

Plz suggest how to tackle this issue...
