problem

Hi all,

I have this problem in FLUENT :

WARNING: Limited wall distance for 241 cells to 1.000000e-12.
Please inspect the wall distance by displaying the
contours of the 'Cell Wall Distance' at the
boundaries. If you observe any irregularities we
recommend the use of an alternative algorithm to
correct the wall distance.
Please select /solve/initialize/repair-wall-distance
using the text user interface to switch to the
alternative algorithm.

Do you know the reasons of this problem?!!!!

Are you running a dynamic mesh? It's a warning that your wall-adjacent cells are too small, and Fluent is calculating a wall distance that is a very small value (which is problematic because it is approaching truncation error).
