Hey!

Generally you can manage grid size in:
details of mesh>sizing>relevance center

And you can change the grid details with (body,face,edge) sizing and some other parameter
It's available in insert!

Hi,
I have the same problem, I have a heat exchanger (helical coil inside a tube ) and I don't know how to reduce the number of elements, to run it with the student version!.

I have tried body sizing increasing the number of elements to the double and it reduces but after that it starts to increase again...
