Minutes

Present: CW, DH, DD (minuter), KS, NB, PB, RK, IM, RNH, FA

Apologies: JB

PB: MixedFunctionSpace([primal, dual])

Currently V * V.dual() == V * V is wrong, and is_primal(V * V) == True goes against the original design. We need a better wrapper class for MixedFunctionSpace (as opposed to WithGeometry) or change what a MixedFunctionSpace is in ufl. The PR where we introduce V.reconstruct() should not address this.

The PR reconstruct FunctionSpace is involved with this issue.

DD: about the petsc message errors in `firedrake_adjoint` tests.

Actually, the test message error appears for every single firedrake tests. For an unknowing reason (at least for me) the flag python3 -m pytest --cov hides (or fixes?) these message errors in firedrake tests. The original problem is in petsc4py.init(sys.args). See the PR #3260

DH suggestion: Try to give the arguments from petsc.
