piyusharas is on a distinguished road
I am simulating a transient multiphase flow in which I am getting rough solution for transient formulation at 1st order implicit and pressure at 2nd order.
When I set transient formulation to second order I get error - amg divergence i x momentum and pressure . My under relaxation factors are already 0.1 for pressure momentum and volume fraction.

What should I do to get better solution.

Thank u in advance
