I have multiphase simulation on openfoam using multiphaseEulerFoam solver with following phase, water(continous phase), air and solid particle(dispersed phase). My simulation is process of flowing dispersed phases in continous phase. When i tried to change the density value of solid phase to higher value, the simulation went diverge when t = 3.0s , then i try to increase the density again, and the simulation went diverge when t = 2.0s, why did this happen theoretically? what should i concern or change to make my simulation stable no matter the density value is?
