Hi,

I used mesh adaptation tool and I got good new adapted mesh.
If I run the Su2 with new mesh from initial it converges. However, If I try to run SU2 from converged solution of parent mesh, It diverges.

I realised that SU2_MSH creates a new adapted mesh and new restart_flow.dat. It has to work but solution could not start from the new restart_flow.dat.

Thanks.

Have you ever tried by disabling multigrid option?
