Adjoint solver convergence issue

Alasdair G · April 9, 2019, 06:10

Hello,

I'm running a batch file to optimise the flow over a 3d wing using the adjoint solver in fluent, however I cannot get the adjoint solution to converge. I have reduced the number of cells to 2.5 million and attempted to use different stabilization schemes to no avail. In the past I managed to quite easily optimise an aerofoil section, but I cannot get this 3d wing to work.

Has anyone used the software for a larger number of cells? If so do you have any advice?

Thanks,
Alasdair

hello
my question is can i use adjoint solver in case of dynamic mesh
