Paraview recorder

[MUz]

Hello,

I would like to visualize an OpenSeesPy geotechnical model (i.e., with UCSD quad materials plus constraints) in Paraview and have tried to implement the PVD recorder as indicated in the OpenSeesPy online documentation, but this does not go through as I receive a warning that "the PVD recorder cannot be read".

Would anyone be able to contribute a functioning example of OpenSeesPy code implementing the recorder?

Thanks.

I'll attempt a minimal example using paraview.

This will record nodal displacements and element stresses to vtk files in the `soilcolumn/` subdirectory.

Load `soilcolumn.pvd` into paraview

Code: Select all

import os
import openseespy.opensees as ops

#
# Define your model
#

# Create an output directory
filename = 'soilcolumn'
if not os.path.exists(filename):
    os.makedirs(filename)
ops.recorder('PVD', filename, 'disp', 'eleResponse','stresses')

The PVD recorder will slow down the analysis significantly, so comment out the recorder command if you're not going to use it.
