hi guys..i usually get error messages when i enter values during preprocessing in fluent...and error messages normally reads out as 'floating point exception'...my question is..how do i check exactly what is the cause of the error to pop up? is there some sort of a debugging function for fluent that i can just check the error?? thanks....

(1). Why not try to calculate a case with exact solution, and input the exact solution as the initial guess. (2). In this case, you should be able to know whether it is going to give you the error message or not. (3). Try also to put in some reasonable numbers in as input. (zero or small numbers are to be avoided in this check out. But you could input zero and check the reaction from the code.)
