Would any one know why they appeal the message "Floating point error-invalid number" whenever I try to shown the contour. Thanks so much.

In particular if there is 1/x and x=0.

Re: Floating point error-invalid number
So where should have that problem, do you have any ideas that where it come from?

Re: Floating point error-invalid number
Probably bad code. If it's yours, use a debugger to trap the error. If you bought it, report the error to your vendor.

Specifically, if it's your code and it's written in Fortran, check that all your functions/subroutines have IMPLICIT NONE in them.

Re: Floating point error-invalid number
If this is a commercial plotting package like tecplot make sure you're not passing it results from a failed CFD run. That's the message tecplot spits out when you try to plot results from a run that has blown up.

Hi Steve,

If it's Fluent spewing out bad values, send the problem to them. That's why you pay them.

Floating point error: invalid number
:( hi all, I had same problem in fluent with a difference that my geometry is bended tube and my fluid is petroleum that part of this non-newtonian liquid is evaporate and this is two phase flow model - mixture.
I solve this problem by change (x or y direction) vector direction for mixture to Normal boundary in boundary condition menu for inlet
and i use adaption to solve this problem.
of course some times the ram are fulled when iteration is done or cpu or hardware is weak. for more help or detail go to following links
good luck dears
