# 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:

$\frac{\partial\mathbf{u}}{\partial t} + \sum_{k=1}^3 \mathrm{A}^{(k)}(\mathbf{u}) \frac{\partial\mathbf{u}}{\partial x_k} = 0$

where $$\mathbf{u}$$ is the unknown vector and $$\mathrm{A}^{(1)}$$, $$\mathrm{A}^{(2)}$$, and $$\mathrm{A}^{(3)}$$ are the Jacobian matrices.

## Install¶

Clone from https://github.com/solvcon/solvcon:

$git clone https://github.com/solvcon/solvcon  SOLVCON needs the following packages: A C/C++ compiler supporting C++11, pybind11 Git master, Python 2.7/3.5, six 1.10.0, 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+. A script at contrib/conda.sh is provided to install the dependency with Anaconda. The following command builds and installs SOLVCON: $ python setup.py install


• Unit tests need to be run with local build:

$python setup.py build_ext --inplace$ nosetests --with-doctest

• Building document requires Sphinx 1.3.1+, pstake 0.3.4+, Sphinxcontrib issue tracker 0.11, and graphviz 2.28+. Once the binary of SOLVCON is built, the following commands can build the document:

\$ make -C doc html


The document will be available at doc/build/html/.
