postproc.py script

This is a script for quick Mayavi-based visualizations of finite element computations results.

Examples

The examples assume that run_tests.py has been run successfully and the resulting data files are present.

• view data in output-tests/test_navier_stokes.vtk

  $ python postproc.py output-tests/test_navier_stokes.vtk $ python postproc.py output-tests/test_navier_stokes.vtk –3d

• save a snapshot image and exit

  $ python postproc.py output-tests/test_poisson.vtk -o image.png -n

• save a snapshot image without off-screen rendering and exit

  $ python postproc.py output-tests/test_poisson.vtk -o image.png -n –no-offscreen

• create animation (forces offscreen rendering) from output-tests/test_time_poisson.*.vtk

  $ python postproc.py output-tests/test_time_poisson.*.vtk -a mov

• create animation (forces offscreen rendering) from output-tests/test_hyperelastic.*.vtk

  The range specification for the displacements ‘u’ is required, as output-tests/test_hyperelastic.00.vtk contains only zero displacements which leads to invisible glyph size.

  $ python postproc.py output-tests/test_hyperelastic.*.vtk –ranges=u,0,0.02 -a mov

• same as above, but slower frame rate

  $ python postproc.py output-tests/test_hyperelastic_TL.*.vtk –ranges=u,0,0.02 -a mov –ffmpeg-options=”-r 2 -sameq”
