Problem with adjointOptimisationFoam

Chris.W · September 28, 2020, 11:21

Hello,

I am quite new to OpenFoam and am currently writing my master thesis.
I would like to use adjointOptimisationFoam to optimise a rather complex geometry of an inner flow for pressure loss.
I have taken over boundary conditions from the tutorial case.

I get a conjugate solution for the normal equations for a first order solver. With the adjoint equations it converges at first and at some point the time step continuity error becomes very large and the calculation stops.
In the log I get the following error message (see picture)

Does anyone have any suggestions?
Thank you!
Chris

I am also having the same issues. It would be really nice if we could get a bit of light here...
