SOLVCON¶
SOLVCON is a collection of conservation-law solvers that use the space-time Conservation Element and Solution Element (CESE) method [Chang95]. The equations to be solved are formulated as:
where is the unknown vector, , , and the Jacobian matrices, and the source term.
Install¶
Clone the hg repository from https://bitbucket.org/solvcon/solvcon:
$ hg clone https://bitbucket.org/solvcon/solvcon
SOLVCON needs the following packages: gcc 4.3+ (clang on OSX works as well), SCons 2+, Python 2.7, Cython 0.16+, Numpy 1.5+, LAPACK, NetCDF 4+, SCOTCH 6.0+, Nose 1.0+, Paramiko 1.14+, boto 2.29.1+, gmsh 2.5+, and VTK 5.6+.
In the contrib/
directory, you can find the scripts for installing these
dependencies:
The binary part of SOLVCON should be built with SCons:
$ scons scmods
Then add the installation path to the environment variables $PATH
and
$PYTHONPATH
.
Additional build and tests:
Building document requires Sphinx 1.1.2+, Sphinxcontrib issue tracker 0.11, and graphviz 2.28+. Once the binary of SOLVCON is built, the following commands can build the document:
$ cd doc $ make html
The built document will be available at
doc/build/html/
.Unit tests should be run with Nose:
$ nosetests
Another set of tests are collected in
ftests/
directory, and can be run with:$ nosetests ftests/*
Some tests in
ftests/
involve remote procedure call (RPC) that uses ssh. You need to set up the public key authentication to properly run them.
