Hi,

I am currently doing an LES simulation of a flow from a supersonic nozzle.

I am using the Implicit formulation. My boundary conditions are pressure-inlet and farfield-pressure for the inlet and outlet. The time step I set is at 1.0e-8.

After about 210000 iterations, i received an error:

Internal error at line 1610 in file 'dbns/rp_mstage.c' on Node 18.
Divergence detected in AMG solver
Internal error at line 1610 in file 'dbns/rp_mstage.c' on Node 103.

Can anyone assist me in this issue? It will be greatly appreciated!!

Thank you
