I was working with dolfin downloaded from conda-forge fenics. Then I needed MeshView and MixedFunctionSpace and I got dolfinx working but couldn’t find the attributes MeshView and MixedFunctionSpace there. Is it still possible to get MeshView and MixedFunctionSpace for dolfin via conda-forge? I have versions conda 22.11.1 and dolfin 2019.1.0.
There hasn’t been a release of dolfin since the introduction of mixed dimensional methods.
This is mainly due to all development moving to DOLFINx.
I am trying to make the appropriate tags needed for a final legacy fenics release, but it has taken more time than expected.
Hi, thanks for your reply.
If I understand it correctly then it is not possible to use dolfinx from conda-forge for MeshView and MixedFunctionSpace but it is with the latest dolfin/Fenicsx built from source? Since dolfinx from conda-forge doesn’t seem to have either.
You can build from source, or use docker, for instance the image:
which is based on the latest commit of
dolfin, built with this recipe:
