Detailed Description

A helper class that returns the coordinates of an element's Gauss points, tailored to be used inside a loop over a set of elements.

Use it like: GmVector ipCoord; GmMultiGaussCoordinates egc(mesh, ruleSet, nodeAc); GmForeachElement(const GmElement* e, mesh) { egc.setElement(e); for(int ip = 0, nip = egc.numPoints(); ip < nip; ip++) { egc.coord(ip, ipCoord); // Fills ipCoord with the cartesian coordinates of the Gauss point ip for element e } }
