J-P, I should not have given Mesquite such short shrift in my reply yesterday. With regard to the MappingQEulerian approach, I would imagine Mesquite would take the mapped points as the mesh points (basically, what my figures show as the mesh), then smooth those out a bit, and return new vertex locations. Then I would need to update the euler_vector to reflect the new vertex positions - this seems to me like a difficult step since the euler_vector describes displacements of degrees of freedom rather than vertices. My difficulty comes from not truly understanding how to think about degrees of freedom in that euler_vector in relation to my naive view of the descriptors of a mesh - i.e. vertices.
This of course begs the question of how the hell am I going to fix my mesh if I don't understand the relation between dofs and the vertices I am not happy with! I'll be working on this at my desk, any further discussion would be appreciated! Also, thank you again for offering help with adding Mesquite to dealii. My reluctance to immediately take you up on this offer is that I am afraid of going down a rabbit hole, although I acknowledge that the solution to my mesh problems most likely lies deep in a tunnel somewhere.
