Hi

I am running the AD solver in RANS mode to compute the drag sensitivities of onera M6 wing. I have validated the case given in

https://su2code.github.io/tutorials/...ined_NACA0012/

for the naca0012 airfoil. For the onera case validation I am using the grid provided in the testcase suite

https://su2code.github.io/tutorials/Turbulent_ONERAM6/

However when I run the case the adjoint solver blows up. I have tried many options like changing the cost functional, reducing the CFL for the adjoint solver, changing the discretization but none seems to work. I am hereby attaching the cfg file I have used for the latest computation(Had to change the extension to .txt). Any insights will be highly appreciated.

Regards

Thanks,
That is surprising!
Can you please share the .cfg file details..or is it the same file as the one I shared?

regards

Absolutely fine!..we get the results of the tutorial gives for the continious adjoints. Only having trouble with the discrete adjoints. Please do run the discrete_adjoint.py with the setting given in the .cfg file I have posted you would notice a blow up of the adjoint solver..
