Here's the images sylvester..what do you think? Although the simulation has already "diverged" (take a look to the magnitudes) the problem starts from there..in that edge inlet and outlet patch...

I'll upload them as soon as possible! :) by the way it seems that the divergence occurs at the farfield to you too..did you fix the problem in some way?

Hi again sylvester..I wanted to tell you that the divergence starting from the "spot" has disappeared. Actually, it turned out that checkMesh was failing with the non-orthogonality error..once I've...

Dear sylvester,

I'm performing shape optimization, not topological optimization as performed by adjointShapeOptimizationFoam solver, so I don't have the alpha field.

Instead, I can confirm you...

Sure sylvester!

This is, I think, the most conservative configuration that I could use. I've also tried to put "1" instead of "0" in the limited schemes but nothing changed. I post you a...

Hi thanks for your answer! My simulation is steady-state, so, where could I use Euler method? I was thinking about upwind method instead; could it be correct?

The error is about the adjoint...

Exclamation Problem with diverging simulation

Hi to everyone guys, I really need some help! I'm running a 3D simulation with adjoint NS equations, but the simulation diverges (residuals seems to remain constant but the error explodes). I've...
