Dear David,

I have just updated firedrake using the branches you mention in the email below but I now get some error related to the mesh (?), when running various codes which were previously working. Any idea what this is?

Thanks, Anna.

    mesh.init()

A brief status update on this: the real-function-spaces branch of Firedrake taken together with the globals_petsc_changes branch of PyOP2 no longer exhibits the direct crash observed. However I am also yet to actually successfully solve using a block preconditioner. I need to consult with Lawrence to establish whether the problem is another bug or pilot error.

Regards,

David

This appears to be more involved than I had first thought. So no luck yet, sorry! David and I need to find some time together to work out the differences/corner cases.

Cheers,

Lawrence
