PWSCG

This project contains an implementation of the PWSCG finite element method.

Plane Wave Semi-Continuous Galerkin is a finite element method using complex exponential plane wave functions as basis functions instead of the conventional polynomial basis functions.

Method is described in this thesis.

Dependencies:

• GetFEM++ (home.gna.org/getfem/)
• scons (for building) (www.scons.org)

Build:

$ scons

Main binary will be available as build/pwscg.

Usage:

$ pwcg {-p} {-z} {-n <subdiv>} {-s {<n>}+}+ -{k{,1,2,3},f,u}{r,i} <expr>

-p      Use linear polynomials instead of plane wave basis functions.
-z      Skip computation of error norms.
-n      Number of times to subdivide grid before output.
-s      Followed by a sequence of numbers, specifies the grid size of the
        simulation. Can be specified multiple times to run simulation several
        times on different grids.

-{k{,1,2,3},f,u}{r,i}
        Set the expression for `k`, `k1`, `k2`, `k3`, `f` or `u`. If suffix is
        `r` sets real part, if suffix is `i` sets imaginary part.
