I solved high residuals issue. thanks WillT !!
But I mistaked, my mesh has 7M points (checked in paraview).
And I saw [How can I know the DoFs with .pyfrs file - #2 by fdw] this page.
I checked my mesh’s DoF
then DoF = (64 X 4 X 105070) + (40 X 4 X 11900) = 28,801,920 (28M) Right?
Is it enough to solve this SD7003 airfoil (Re=60,000) case?
