I'm passing a subclass of FunctionBase<Number> to a DirichletBoundary object, and the FunctionBase<Number> uses a MeshFunction from a separate (dim-1)-dimensional mesh to return a value. In this context, the lower-dimensional mesh "matches" the relevant boundary of the dim-dimensional mesh.
I sometimes have some tolerance issues, so that I have to find the "nearest point" in the (dim-1)-dimensional mesh. At present, I just find the "nearest node" on the (dim-1)-dimensional mesh (rather than the nearest interior point or whatever), and it works fine. I gather that this is because (at least in my case) the DirichletBoundary only evaluates the FunctionBase at the nodes on the boundary of the dim-dimensional mesh. I'm wondering if this will be true in general, or if this is just due to the fact that I'm using nodal (i.e. LAGRANGE) basis functions in this case? Thanks!
