Hi all, I'm simulating a multiphase flow in a section-changing tube. I've made several simulations but all of them crashed at the same simulating time (approx. 2.45s). I tried already to switch to second order solver and remesh the domain. the error message I encounter at the simulation crash is "floating point error". thx in advance austin

try to give realistic second phase volume fraction. Use some standard correlations available in literature to give volume fraction BC.

thank you for your answer, but can you be more specific?
