FPL is a collection of routines for plotting data on finite element method (FEM) meshes. It provides routines for outputting files and displaying data in OpenDX (IBM Visualization Data Explorer) and VTK (Visualization Toolkit) formats. It allows displays of triangular and tetrahedral meshes, as well as scalar and 2D vector fields.

This Octave add-on package is part of the Octave-Forge project.
