Hello Now FENICS has changed the name of vtkplotter to vedo, now it cannot run your code, can not import datadir from vtkplotter, I want to know the FENICS version you use

I used Fenics 2019 for these sims. I would recommend migrating to Fenicsx. See https://github.com/Woodchuk/Fenicsx for an example (more to be added later).

Now I'm just starting to learn FENICS, and FENICSX documentation is much less than FENICS, so the FENICS version I installed is 2019.2.0.dev0, and I'm having a lot of problems trying to run your code. After I solved the vtkplotter problem, now the Solution failed to converge in 0 iterations, I don't know if it is a version problem. Instead of asking questions in the forum, it may be more effective to ask you directly. ` DOLFIN encountered an error.
