Minutes

Present: DD, KS, IM, JB, DH, NB, PB

Apologies:

JB: We need to keep an eye on CI runtimes

CI has been very inconsistent with runtimes lately.

DH: Perhaps switching from disk cache to memory will help to understand what is happening.

Another issue: VertexOnlyMesh is expensive in time in CI.

PB: Complicated duals

From this issue I encountered found several bugs:

1. One of the latest commits to FEniCS/ufl has bugs within {Action|Adjoint}.ufl_domains()
2. We fail to extract the correct number of arguments of complicated FormSums
3. In some parts of the code (Adjoint.__new__, Action.__new__), we forget about the weights of a FormSum

• Discuss about adj_input

Merge PRs

Note that PRs put in this section should either be trivial or already have been reviewed. Discussion-worthy PRs should be separate agenda items. JB: Namespace FML

Merged.
