I am trying to recreate the demo problem from @dokken 's tutorial for subdomains. That tutorial uses an external mesh and solves the poisson equation with variable coefficients. However, I was trying to develop this demo in FEniCs dolfin instead of dolfinx, so that I can go back and forth between th…

@dokken I was just reading this in the dolfin docs, https://fenicsproject.org/olddocs/dolfin/latest/python/demos/subdomains-poisson/documentation.html?highlight=subdomains . Is this still a valid way to do things? I can see how this maps to the example that you gave, with the MeshFunction and Subdom…

The approach is still valid in legacy dolfin.
