Do you have any idea why sometimes a step files imports with no quilts? Just curves.

More information maybe helps. A step file had a boolean...

What do these colors indicate?

Not sure if it helps your case, but had similar problem a while back.

If you use MG_ADJFLOW= YES it could be that. Run it with different number of cores like 12.

set TIME_DOMAIN= NO and run it and see if it converges.


Then, if so set TIME_DOMAIN= YES without UNST_CFL_NUMBER.



I wasn't using UNST_CFL_NUMBER only TIME_STEP.

Try with ENTROPY_FIX_COEFF= 0.5 and CFL_NUMBER= 2.0

L2ROE for me works. Though I have a course grid. You also can plot residual and see where they get stuck.

Also extra point on SU2_DEF.



It doesn't write the whole mesh when more cores than a node being used. I just had to keep SU2_DEF and SU2_DOT_AD running in serial.

I also think the same way. I have to do the sensitivity analysis through MeshLink.
I am thinking what is the best way to obtain sensitivities. I know some do finite difference.
