But the residual for energy is diverging! How to deal with this? Thanks a lot! The simulation settings are following below: 1, operating pressure is 101325Pa. 2, mass flow inlet, pressure outlet. 3, grid number is 0.3million, determinent 222>0.4,Angle>32. 4, the corrant is 0.01, the relaxation keep the defualt value. 5, the density of helium is ideal-gas, the viscosity is sutherland. So where is the problem?
