resview.py script

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

Examples

The examples assume that python -c "import sfepy; sfepy.test('--output-dir=output-tests')" has been run successfully and the resulting data files are present.

• View data in output-tests/test_navier_stokes.vtk:

  $ python resview.py output-tests/navier_stokes-navier_stokes.vtk
  

• Customize the above output: plot0: field “p”, switch on edges, plot1: field “u”, surface with opacity 0.4, glyphs scaled by factor 2e-2.

  $ python resview.py output-tests/navier_stokes-navier_stokes.vtk -f p:e:p0 u:o.4:p1 u:g:f2e-2:p1

• As above, but glyphs are scaled by the factor determined automatically as 20% of the minimum bounding box size.

  $ python resview.py output-tests/navier_stokes-navier_stokes.vtk -f p:e:p0 u:o.4:p1 u:g:f10%:p1

• View data and take a screenshot.

  $ python resview.py output-tests/diffusion-poisson.vtk -o image.png

• Take a screenshot without a window popping up.

  $ python resview.py output-tests/diffusion-poisson.vtk -o image.png –off-screen

• Create animation from output-tests/diffusion-time_poisson.*.vtk.

  $ python resview.py output-tests/diffusion-time_poisson.*.vtk -a mov.mp4

• Create animation from output-tests/test_hyperelastic.*.vtk, set frame rate to 3, plot displacements and mooney_rivlin_stress.

  $ python resview.py output-tests/test_hyperelastic_TL.*.vtk -f u:wu:e:p0 mooney_rivlin_stress:p1 -a mov.mp4 -r 3
