hi all, currently i set up a case for a mold filling simulation using vof with piso velocity pressure coupling, presto pressure discretization, first-order in time and second order discretization in space,CICSAM for volume fraction with default under relaxations. i used quite fine tetra mesh with a max skew.<0.8 and then convert all domain to polyhedral.At the first time step, except the continuity,velocity and energy are converged. What may the problem, please help regards ali
