collapseEdges (after makeAxialMesh) not worked

mechy · June 23, 2011, 17:12

I have used makeAxialMesh to run flow in pipe at first I create 2D mesh and then Run
makeAxialMesh -axis lower -wedge frontAndBack -overwrite
mesh is created successfully but when I run
collapseEdges 1e-4 179.5 -overwrite

I encountered bellow error
Create time

Create polyMesh for time = 0

#0 Foam::error:

Thanks for the unset command trick, that seemed to work
