Dear friends I hope that someone can help me regarding the folloing problem. I am trying to solve two phase liquid gas problem for my atomizer. Now with a certain mesh size I am able to solve one case of higher pressure (90psi injection pressure) injecton, but when i tried to solve the same problem without any changes in grid size for lower pressure values (60psi and 30psi injection pressure) it gives me error after around some few thousand time step regarding convergence detected and then again i stringent my residual value to get acurate result then again after few time step it gave me floating point error. I adapt grid and try to solve the lower pressure case but it gave me the same floating point error.Can anyone help me and suggest me how to overcome this problem. Please send some necessary step and suggestions Thank with regards viv.
