Hello everybody,

I try cfMesh and it appears to be very powerful tool.

I have a question: is there any way to disable boundary layer generation?
When I use the similar geometry and the same meshDict file, sometimes it generates two cells boundary layer along boundaries. Sometimes it does not generate this layer. I would like to disable layer generation since it produce cells of high aspect ratio, which is strongly vary along the surface. (see layer.jpg).
nolayer.jpg is the case in which these layers are not generated. I would like to have this kind of behavior each time, but do not know how to control it.

No boundary layer parameters are specified in meshDict file.

Thanks in advance.

meshDict is very simple:

surfaceFile "dome.stl";
maxCellSize 0.04;
keepCellsIntersectingBoundary 1;
enforceGeometryConstraints 1;

cellSize 0.03;
