unsigned int idx (const ElemType type, const unsigned int nx, const unsigned int i, const unsigned int j)

Function Documentation

unsigned int MeshTools::Generation::Private::idx (const ElemTypetype, const unsigned intnx, const unsigned inti, const unsigned intj) [inline]A useful inline function which replaces the #defines used previously. Not private since this is a namespace, but would be if this were a class. The first one returns the proper node number for 2D elements while the second one returns the node number for 3D elements.
