Hi everyone,

I am trying to perform a shape optimization with continuous adjoint method based on displacement of FFD points. I am working with SU2 Falcon on Windows 10.

The geometry and the FFD are shown in the following image.



During the first optimization iteration, while SU2_CFD is running for adjoint computation, I get the following error. The error disappears if the code is executed with a low number of processor (less than 5).

I attach also the configuration file and log_adjoint.dot file where the following error appears.

Do you have any suggestion? How can I solve this problem? Thank you in advance.
