Hi,

I am a new user of OF-4.1 and I am trying to create a free surface inside a box (unstructured grid) using interFoam.
I have used a similar box with structured grid and it works perfectly fine.
But for my unstructured box I have issues, I used the same boundary conditions from the structured box but the results are diverging. I don't what could be the issue.

Here are a screenshots of the unstructured box:

I have changed the boundary conditions for the outlet (I used totalPressure), but I still have a problem with the UZ and p_rgh as you can see.

I don't understand what could be the problem. Can someone help me with this issue.

Thank you
