jarjarbinks is on a distinguished road
I am validating a case on cavitation around 2d clark-y airfoil using interPhaseChangeFoam. maxCo=0.45 and timestep= 2e-05 as mentioned in the paper and by using adjusttimestep the simulation runs at 6e-09 timestep which is extremely small. I think there is some problem with mesh or boundary conditions. Kindly let me know if any particular file is required(p,u,transportproperties,etc). I have employed les, vof andkunz model for my sim.

Thank you.
