Hi Shaun,

a bit long your post... but I have a similar problem for a air intake channel. Would be nice, if someone has an idea?

Hello Fabian, I thought I needed to provide enough detail about the setup etc to allow some one with a bit more experience to diagnose the problem.

I tried limiting the values of 'p' in the interpolation sub dictionary but found it did not help. I have tried reducing the complexity of the problem and this did work in removing the bounding p statements for a while. It did diverge again after I started increasing the under relaxation parameters back to something more reasonable that would not restrict the evolvement of the solution variables.

Perhaps I just need more patience in getting a stable solution before increasing the complexity of the physics again.

Does anyone have any further comments perhaps?
