I have a problem about apply pressure to an lean boundary in weekly compressible navier stokes model. It does work when applying pressure to a horizontal boundary as well as vertical boundary. However, when the boundary has a certain angle to the X-axis, it is failed to find a solution no matter what the pressure is (constant or function). The other settings are the same. Here is the Error information:

Failed to find a solution:
No convergence, even when using the minimum damping factor.
Returned solution has not converged.

Did anyone encountered this kind of problem? How to solve it?

Any of your suggestion will be highly appreciated!
