Helium Water multiphase causes divergence
 

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
