PyClaw comes with many example problem scripts that can be
accessed from the module clawpack.pyclaw.examples.
If you have downloaded the PyClaw source, you can find them
in the directory clawpack/pyclaw/examples/.
These examples demonstrate the kinds of things that can be done
with PyClaw and are a great way to learn how to use PyClaw.
Running and plotting examples
Interactively in IPython
- ::
from clawpack.pyclaw import examples
claw = examples.shock_bubble_interaction.setup()
claw.run()
claw.plot()
To run and plot a different example, simply replace shock_bubble_interaction
with another example name. A number of keyword arguments may be passed to
the setup function; see its docstring for details.
These usually include the following:
use_petsc
: set to 1 to run in parallel
solver_type
: set to classic or sharpclaw
iplot
: set to 1 to automatically launch interactive plotting after running.
Note that this shouldn’t be used in parallel, as every process will try to plot.
htmlplot
: set to 1 to automatically create HTML plot pages after running.
outdir
: the name of the subdirectory in which to put output files. Defaults to
‘./_output’.
From the command line
If you have downloaded the Clawpack source, you can run
the examples from the command line.
Simply do the following at the command prompt:
$ cd clawpack/pyclaw/examples/acoustics_1d_homogeneous
$ python acoustics.py iplot=1
You can run any of the examples similarly by going to the appropriate directory and
executing the Python script. For convenience, the scripts are set up to pass any
command-line options as arguments to the setup function.
List of built-in examples
You can see results from many of the examples in the Galleries of all Clawpack applications.
