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).
