Pyclaw

Installation:

pip install clawpack

To run an example, launch an IPython session and then:

from clawpack.pyclaw import examples
claw = examples.shock_bubble_interaction.setup()
claw.run()
claw.plot()

PyClaw is:

  • A hyperbolic PDE solver in 1D, 2D, and 3D, including mapped grids and surfaces, built on Clawpack;
  • Massively parallel – the same simple script that runs on your laptop will scale efficiently on the world’s biggest supercomputers (see Running in parallel);
  • High order accurate, with WENO reconstruction and Runge-Kutta time integration (see Using PyClaw’s solvers: Classic and SharpClaw);
  • Simple and intuitive thanks to its Python interface.

PyClaw makes use of the additional Clawpack packages, Riemann and VisClaw for Riemann solvers and visualization, respectively.

If you have any issues or need help using PyClaw, contact us.

Riemann Solvers reference documentation

The Riemann solvers now comprise a separate package. For convenience, documentation of the available pure python Riemann solvers is included here. Many other Fortran-based Riemann solvers are available.
