Re: [Libmesh-users] DirichletBoundary API

[Dmitry K. <ka...@mc...>]

Right now DMlibMesh doesn't mesh with the mesh much, but allows to define
splits based on mesh block and/or variable. It's a bit dated and should be
replaced with the equivalent of DMMoose that's a bit more user-friendly and
advanced. I'm not sure how DirichletBoundary would interact with it, but I
can take a look, if anything starts breaking.

Dmitry.
