Plotting

PetClaw output can easily be plotted using the pyclaw plotting routines in Clawpack. It’s also possible to plot the solution using PETSc.

Plotting with Pyclaw

Pyclaw includes routines for creating HTML and LaTex plot pages or plotting interactively. These require a setplot.py file that defines the plotting parameters; see this help page <http://kingkong.amath.washington.edu/clawpack/users/setplot.html> for more information. Once you have an appropriate setplot.py file, there are some convenience functions in $PETCLAW/src/petclaw/plot.py for generating these plots. Assuming you have output files in ./_output (which is the default), you can generate HTML plots from Python via

>>> from petclaw import plot
>>> plot.plotHTML()

This will generate HTML pages with plots and print out a message with the location of the HTML file. To launch an interactive plotting session from within Python, do

>>> from petclaw import plot
>>> plot.plotInteractive()

Plotting with PETSc

For now the PETSc plotting can only be done using a pyclaw.controller object in memory (not from PetClaw output files). Assuming you are in Python with a pyclaw.controller object named claw, this is done via

>>> from petclaw import plot
>>> plot.plotPetsc(claw)
