When you try to plot the mesh using Pyvista,
Error displaying widget error appears in the Jupyter notebook. For example : Test problem 1: Channel flow
The recommendation suggested by @dokken in here is also not working anymore. (It did work well until now!)
However, when you change the backend to
pyvista.set_jupyter_backend("ipyvtklink")
pyvista.start_xvfb()
it works.
Is this a problem with my computer or has something happened with the Pyvista backends?
Appreciate your help
