Hi John, Thanks for your recommendations. I think MOOSE library is a good choice for me to take a look further. So far I am not sure how much I can do inside the framework of MOOSE library. I think I will try to implement codes in MOOSE library first and gain experience of it. My ultimate goals are on applications to solve relatively large scale fluid-structure interaction problems. I will try MOOSE first.

I am planning to write a fluid-structure interaction (FSI) solver under arbitrary lagrangian-eulerian (ALE) description. I noticed libmesh is a sophisticated FEM library. There are so many publication based on this library. However, I did not find a publication of monolithic ALE-FSI solver using libmesh library. I understand I can couple it with another software. However I prefer to the monolithic formulation. I find that libmesh indeed has a class "libMesh::DifferentiablePhysics" to deal with ALE formulation. It will be really good, if there are more helpful examples codes. Could anyone give some suggestions? Is libmesh a good choice to start coding a ALE formulation with dynamic mesh? Thanks in advance. 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... -- John _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
