fem3d_project, a C++ program which projects a function F(X,Y,Z), given as tabulated data, into a space of piecewise linear tetrahedral elements associated with the finite element method (FEM).

Source Code:

LINEAR starts with sample data for the vector function f(x)=[ 1, 2x, 3y, 4z ], on an 8x8x8 grid of equally spaced nodes from [0.0,8.0]x[0.0,8.0], and projects this onto a piecewise linear finite element meshes defined on equally spaced grids of dimension 4x4x4, 2x2x2 and 1x1x1.
