I have checked out some of the available libraries, but I want to work with the latest petsc-dev version and I am sure there will be many incompatibilities. So far I think I'll end up working with one of these libraries: SAMRAI, Chombo, libMesh and deal II. Before I start checking out each of them and learn how to use them I though I would ask you guys which one you would recommend. My code would be a finite element analysis in solid mechanics. I would like to take full advantage of petsc capabilities, but I would not mind start with some restrictions. I hope my question is not too broad.</div>
