hello everyone,

I would like to check the adjoint gradients against the FD ones. To do so I use the python scripts to compute the gradients. However, I would like to save some time by avoiding to compute the direct solution since I already have that results stored in a solution_flow.dat file from previous simulations.

Is there a way to deactivate the computation of the direct solution?

Thanks in advance,

Z

Maybe you can just adjust the convergence criteria (changing RESIDUAL_MINVAL)... so the solver will only perform a couple of iterations.
