fem1d_project, a FORTRAN90 code which projects a function into a function space associated with the finite element method (FEM), using least squares or projection methods, especially for cases in which data must be transferred from one mesh to another.

Source Code:

• fem1d_project_test.sh, runs all the tests.

POWERS starts with sample data for the vector function f(x)=[ 1, x, x^2], on a grid of 11 equally spaced nodes from 0 to 10, and projects this onto a piecewise linear grid of 6 equally spaced nodes from 0 to 10.
