PyWENO

PyWENO is a Python module for computing high-order Weighted Essentially Non-oscillatory (WENO) reconstructions of cell-averaged data arrays.

The basic interface provides a simple routine to compute 1D reconstructions at various points within each grid cell. The points at which the basic interface can reconstruct the original function at include: left edge, right edge, Gauss-Legendre quadrature points, Gauss-Lobatto quadrature points, and Guass-Radau quadrature points.

PyWENO can also be used as a code generator to build custom WENO reconstructors in C, Fortran, and OpenCL on uniform grids.

Prerequisites

To install PyWENO, you need:

• NumPy
• SymPy (optional if you avoid pyweno.symbolic)

Testing

To build PyWENO and create symlinks to the extension modules:

$ python setup.py build $ cd pyweno $ for so in ../build/lib*/pyweno/*.so; do ln -s $so; done

Now, nosetests should work:

$ nosetests
