Thanks! So, would the shape function derivatives account the orientation of the element?
For instance, a 1D element oriented along: x-axis vs y-axis vs x=y line. In all cases, there is only one shape function defined along the element coordinate. But its derivative wrt x and y will vary. Is this handled for both 1st order and 2nd order Lagrange (for instance)? -Manav > On Feb 12, 2018, at 5:06 PM, Roy Stogner <royst...@ices.utexas.edu> wrote: > > > On Mon, 12 Feb 2018, Manav Bhatia wrote: > >> I was looking through some code in FE and noticed some comments >> about 1D/2D elements in 3D space.
