Helium Water multiphase causes divergence -- CFD Online Discussion Forums

hr_nt New Member HR Join Date: Nov 2022 Posts: 17 Rep Power: 3	Greetings to all ! I am trying to run a multiphase simulation with helium and water using interFoam. I am running into issues with convergence of the solution as the solution diverges in which the timestep required to keep Co number below 1 reduced to a very low value such as 1e-30. I suspected this to be a issue with the gas and ran the exact same simulation with air as the gas. This simulation converges without any issues. Please advice
