Hi all, My libMesh is a little rusty, and I need to work out how to get a solution value at a nonquadrature point. I have looped over the elements of the mesh to locate the element that contains (x1,x2) and then I use an inverse map to get the point in the reference element corresponding to (x1,x2), i.e.: Point x_point(x1,x2,0); Point ref_point = inverse_map(elem,x_point); But then I can't recall how one can retrieve the basis function values at ref_point rather than the quadrature points. A pointer would be appreciated :) Regards, David
