This distribution contains the Excafé library.

Build dependencies include:
- An MPI compiler such as Open MPI (http://www.open-mpi.org/) (for PETSc).
- Boost (http://www.boost.org/)
- The Apache Portable Runtime (https://apr.apache.org/)
- GiNaC (http://www.ginac.de/)
- Triangle (http://www.cs.cmu.edu/~quake/triangle.html)
- PETSc (https://www.mcs.anl.gov/petsc/)
- UFC (https://launchpad.net/ufc)

For the steady_stokes_dolfin example:
 - Dolfin (https://launchpad.net/dolfin)
 - FFC (https://launchpad.net/ffc)

 All the above are installable on a Debian/Ubuntu system from standard
 packages.

To build:
 
If configure is not present, run ./bootstrap
- Run:
 
  ./configure

  then 

  make

The folder 'navier_stokes' contains a coupled incompressible Navier-Stokes
solver that simulates 2D fluid flow around a cyliner.

The folder 'mass_matrix_generator_2d' contains the executable that uses Excafé
to generate mass matrix and Laplacian operator examples for the ACM Transactions
on Mathematical Software paper.
