1. Defining the triangulation in its desired format (I think this is
documented within the Mesquite documentation)
2. Translating this Euler vector into something thats relevant to the
FESystem for your problem (this is what you're struggling to
conceptualise, but its really not difficult at all).
3. Dealing with hanging nodes (which if I recall correctly Mesquite does
support).
In the case that the mesh lives in a higher dimensional space, you also
have to enforce -- either as part of the problem formulation, or as a
postprocess step for the output of Mesquite -- that the new nodes still
need to lie on the geometry as described before. In other words, nodal
points can move *within* the surface, but not perpendicular to it.
I have no idea whether that is possible within Mesquite, but in the
worst case you can always project back to the previous surface.
