hi aerostress82, the issue I am talking about is not Guass Quadrature. Although, if I were to integrate my gradient (which I am talking about) over the element, I would use Gauss Quadrature.
The issue I am referring to is computing the discrete exterior gradient on the element face (in 3D, 3...
Hello all,
I am developing a 3D boundary element program where I have only surface elements (4-node quads and 3-node tris), but that are oriented in 3D space. Likewise, I want to compute x,y,z gradients on each of these faces.
I have a nodal solution (phi), and I want to compute dphi/dx...
