No convergence. Relative timestep too small. Double dogleg solver.

Hello,

I am trying to use Double Dogleg Solver for a Navier-Stokes problem, and even tough the residuals in the convergence plot have reach 100% for the velocity and pressure segregated step, I get the "No convergence. Relative timestep too small" error.

The simulation is almost finished, just waiting on the turbulence segregated step.

I can seem to understand why! Does anyone have any insight on this?

Best Regards,

Rui
