Hi
In the unsteady optimization SU2_DOT cannot compute the gradients. I test all of the provided TestCases. the gradient are always: ---------- Start gradient evaluation using sensitivity information ---------- Evaluate functional gradient using Finite Differences. Design variable (HICKS_HENNE) number 0. DRAG gradient : -nan ------------------------------------------------------------------------- Design variable (HICKS_HENNE) number 1. DRAG gradient : -nan ------------------------------------------------------------------------- Design variable (HICKS_HENNE) number 2. DRAG gradient : -nan I attach the config file for pitching_naca64a010 euler optimization. I just modified the file to calculate 3 time step and then move on to continuous adjoint. It would be great if someone else can run this simulation and check if the same thing happened. the command is: continuous_adjoint.py -f pitching_NACA64A010.cfg -n 2 Thanks alot |
