the followings are the error messages I got
global courant number is greater than 250.00 the velocity field is probably diverging. Please check the solution and reduce the time-step if necessary. i'm trying to solve two-phase flow inside a cylinderical tank which has water jet inlet. i've tried several models but i got the same message. FLUENT cannot calculate even one iteration. help me. |

Hello,
you need to provide more details of your case, steady/transient? vof? explicit? what time step? greetings |

I know this is obvious, but did you try reducing the time step? it will converge slower but it should be more stable.
