Hi Bin Liu,

You may want to look at the FSI work that Cyrill von Planta and
collaborators are doing via the MOOSE library, e.g.

https://www.researchgate.net/publication/338446882_Modelling_of_hydro-mechanical_processes_in_heterogeneous_fracture_intersections_using_a_fictitious_domain_method_with_variational_transfer_operators

In addition to that, Boyce Griffith's research group has developed an
immersed boundary method with the IBAMR library (https://ibamr.github.io/)
which may be of interest to you.

I'm not sure what your ultimate goals are, but I would probably recommend
not starting from scratch with libmesh to solve FSI, as it would likely
require a lot of work...
