Dear Bill
I have tried to use "vertexBoundaryNormal" in order to get the normal vectors
for "circle in a channel, cic" grid. When I diplay the results for the normals
of the channel grid over side=0 on axis0, surprisingly two sets of normals are
printed with one of them showing all -1 and the other all 0 for the normals. I
can not interprete the zeros normal vectors on this side of the cic grid. Could
you please kindly tell me where is my mistake in extracting the normals?
I copy the code and the display output below.
Best regards
Mostafa
#include "Overture.h"
int
main(int argc, char *argv[])
{
Overture::start(argc,argv); // initialize Overture
// create and read in a CompositeGrid
CompositeGrid cg;
getFromADataBase(cg,"cic.hdf");
cg.update(MappedGrid::THEvertex | MappedGrid::THEcenter |
MappedGrid::THEvertexBoundaryNormal);
int grid=0;
int side=0;
int axis=0;
MappedGrid mg = cg[grid];
realArray normal=mg.vertexBoundaryNormal(side,axis);
normal.display();
Overture::finish();
return 0;
}
