HJPACK
a software package for Hamilton-Jacobi Equations

HJPACK allows to run numerical experiments on Hamilton-Jacobi equations in 1D and 2D case. It includes some finite difference and semilagrangian schemes on structured rectangular grids for different kinds of Hamilton-Jacobi equations, mainly in the convex case. Further developments for non convex Hamiltonians and unstructured grids will follow.
Its main components are:
  • a collection of Fortran90 and C numerical routines which compute the viscosity solution for several classes of Hamilton-Jacobi equations in one and two dimensions.
  • a Tcl/Tk graphical interface to help the user in all the steps of the simulation, setting the input parameters, processing the data and visualizing the solution and some relevant data.
  • a Matlab or Octave script for the graphic output.
  • OpenMP directives for the two dimensional parallelization.
