Hi,

Does anybody know how to use SurfaceToCell utility for an irregularly shaped surface. The main problem comes in the definition of outside points. I have an .stl file with tree height information. How to map this using surfacetocell utility. The clarity the syntax of the surface to cell is posted below. Please help!!!

actions
(
{
name porosity1;
type cellSet;
action new;
source surfaceToCell;
sourceInfo
{
file "constant/triSurface/tree.stl";
useSurfaceOrientation false;
outsidePoints ((1000 1200 1000)); // definition of outside ! How to specify this ??
includeCut true; // cells cut by surface
includeInside true; // cells not on outside of surf
includeOutside false; // cells on outside of surf
nearDistance -1; // cells with centre near surf
// (set to -1 if not used)
curvature -1; // cells within nearDistance
// and near surf curvature
// (set to -100 if not used)
}
}
);
