feature/mesh-nullspace commits are not in development

[gthyagi]

Current upstream/development does not contain the mesh-nullspace work that is present on upstream/feature/mesh-nullspace.

Missing commits:

• 2338493b5293dd8c2c61856dd7e66a42b5898bd7 Add nullspace_rotations property to mesh classes
• 4936d8284dd0f62dda42b3342bb4cfe22cfbebdf Add petsc_use_nullspace convenience property to Stokes solver

I verified that neither commit is an ancestor of current upstream/development.

This seems worth flagging because 4936d828 depends on 2338493b:

• 2338493b adds mesh.nullspace_rotations
• 4936d828 uses that to auto-populate stokes.petsc_velocity_nullspace_basis via stokes.petsc_use_nullspace = True

At the moment, development still does not expose mesh.nullspace_rotations or stokes.petsc_use_nullspace, so shell nullspace setup still has to be handled manually.

Tagging @lmoresi for visibility.

Resolved — PR #105 merged mesh.nullspace_rotations and petsc_use_nullspace into development.
