Notes on Installing FENICS onto a Windows machine JH 9/22/2022

All FENICS sims, including code description, implementation, theory, and results, are explained in the User's Manual.

I ran into issues implementing many of these simulations, especially plotting results.
I could not get the displacement solution for ft06_elasticity to plot due to a python error.
I could not solve the error.

Running FENICS: cd to FENICS_FOLDER/pub/python/vol1

Run any of these using similar to: python3 ft01_poisson.py

There are errors in the original FENICS codes. Errors in their code: https://github.com/hplgit/fenics-tutorial/issues/52

Error in ft02: "interactive is not defined", open the .py files and change interactive() to: import matplotlib.pyplot as plt plt.show()

Error in ft03: replace array() with: get_local() replace interactive() with: import matplotlib.pyplot as plt plt.show()

Error in ft04: same as ft03

Error in ft05: same as ft03

Error in ft06: same as ft03, and add to the beginning: from ufl import nabla_div

Potential fixes for plotting errors in ft06: https://fenicsproject.discourse.group/t/how-to-plot-3d-beam-after-deformation-not-colormap/5501/2 https://github.com/marcomusy/vedo/issues/152 https://copypaste.guru/WhereIsMyPythonModule/how-to-fix-modulenotfounderror-no-module-named-vedo
