resview.py script

This is a script for quick VTK-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 resview.py output-tests/test_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/test_navier_stokes.vtk -f p:e:p0 u:o.4:p1 u:g:f2e-2:p1

• view data and take a screenshot

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

• take a screenshot without a window popping up

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

• create animation from output-tests/test_time_poisson.*.vtk

  $ python resview.py output-tests/test_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
