ft06 Plotting Displacement Problem

[amandaivl]

Hi,
I'm trying to do the ft06 elasticity demo, but I am getting the following error when I run the program:
*** Warning: Matplotlib plotting backend does not support displacement for 3 in 3. Continuing without plotting...

Furthermore, when I open the image file for "displacement" it seems to be empty. The other two files (magnitude and Von Mises) seem to work fine. Any thoughts on how I can fix this?

I am using Debian 10 and python 3.

Thanks!

install vtkplotter.
Then, try
from vtkplotter.dolfin import plot
done

Hi, I think your code is

# Plot solution
plot(u, title='Displacement', mode='displacement')
plt.savefig('u.png')
plt.cla

Have you fixed this problem?
