Hello, Sir,

I found that I came upon one problem with my simulation. However , the Fluent told me that : Time Step reduced in 3 cells . And the information went all the down the simulation. How can I solve it? THanks very much.

(1). I think, when the programmer was doing the code checkout, he printed the message after some calculations or the if statement, so

that he could determine whether the logic was executed or not. (2). My feeling is, it is probably not intended for the user of the code. It is

telling the programmer that something has happened. (most likely, it is heading in the wrong direction, the solution is diverging.)
