Is there a place where I can found formalas used for interpolation in the Finite Element Method?
I'm look for recipes, where formulas are given for basic 2D and 3D elements, that can just be applied, without any theory.
In other words, there are a lot of ressoures about Finite Element Method theory available on the web, but I'm looking for a site/document that just give the algorithm for interpolation for the most common case, that I can code directly.
I'm especially looking for interpolation formula for P1 Prism (interpolating from the 6 vertices).
