I have a 1D mesh with top be a wall. What I want is the distance from all cells to that wall. Simple enough?

When I do

testWallDist . test

I got error like this:

--> FOAM FATAL ERROR : Maximum number of iterations reached. Increase maxIter.
maxIter:1000
nChangedCells:0
nChangedFaces:5


From function meshWave<type>::meshWave(const polyMesh&, const labelList&, const List<type>&, const label maxIter)
in file /home/liu19/research/OpenFOAM/OpenFOAM-1.3/src/OpenFOAM/lnInclude/meshWave.C at line 846.

here is the simple test case:

Wall distance travels one cell
 
Wall distance travels one cell per iteration. You have max 1000 iterations set up. How many cells 'thick' is your mesh?

I have 1000 cells in this simple 1D mesh.

The maxIter is not set by me. I found maxIter is set as the mesh cell numbers which I am quite confused.

Here is from src/meshTools/cellDist/patchWave/patchWave.C

meshWave<wallpoint> waveInfo
(
mesh(),
changedFaces,
faceDist,
mesh().nCells() // max iterations
);

Change the maxIter to a bit more than mesh().nCells() and recompile.
