My first comment is: here you are plotting your results, but there is no visual comparison with the reference results, that makes it difficult to say how they compare. If you're discussing a...

The curves of wall heat flux and pressure look close, but they are not completely converging, and their peaks are about 5%-6% different. The Ttr cloud picture is close, but the Tve cloud picture...

You need to have lower residuals. The adjoint can be quite sensitive to left-over errors. I would go to at least 1e-13, preferably 1e-14. You can also see CL still changing so that's an indication...

Hello,


slight differences are probably due to the slight differences in the mesh and, potentially, also lack of further convergence.

Indeed, near the degree=80-90 on the wall, the convergence...

Thanks for your reply.


Yes, I first ran the simulation with MATH_PROBLEM= DIRECT and got a converged result of CL= 0.853490 and CD= 0.011720 99700. So then I used CL = 0.85 as the target lift....

The first step is to check the CFD setup.



Do you have a fully converged CFD simulation (independent of the adjoint setup) for a specified alpha that shows the expected CL (I guess there is...

I have a quick question regarding the restart file in SU2.

I am using a .csv file in order to restart a simulation (combining two meshes to form one without using multizone). I...

Could you maybe show how well it does compared to the validation results from NASA:

They use a very fine grid, and they report results up to a=15
