Hello everyone,
While following the SU2 tutorial series' Design Features, specifically the case "Unconstrained shape design of a two-way mixing channel," I encountered an issue during the fourth step, Gradient Validation. My calculation results: However, the results provided on the website: The results from these two are vastly different, but the script seems to run normally without any error messages. After running the program according to the tutorial, the result is obtained in just one step (although no error messages are displayed, this result clearly isn't what was expected). Is there any issue here? Any suggestions would be greatly appreciated. |

Fortunately, I found the mistake in the first problem. The error was caused by the inconsistency in the finite difference step size between the two scripts. In the gradient_validation.py script, the value was set to 1e-8, while in the postprocess.py script, I had set it to 1e-7 (forgive my oversight).
