Hello everyone,
I am running a CONTINUOUS_ADJOINT problem with two slightly different meshes for the same airfoil. The main difference in those files is the refinement around the airfoil. In the first one, the size of the cells which distance is 1 m from the profile is 0.05 m, in the other one the size is 0.03 m for a distance of 0.5 m. In the first case the adjoint solution is reached in less than 50 iteration, in the other one the solution is not found. I upload the .cfg file and the meshes at this link: https://drive.google.com/file/d/1m9i...ew?usp=sharing Does anyone know why does it happen? |
