Open source adaptive mesh code

Click For Summary
A user is seeking recommendations for open source libraries suitable for parallel code development in adaptive mesh refinement. They are considering OpenFOAM, LLNL/SAMRAI, LANL/CLAMR, and MIT SU2, expressing a preference for leveraging existing solutions rather than starting from scratch. OpenFOAM is highlighted for its flexibility and the abundance of online resources available for implementing adaptive meshing. The discussion emphasizes the importance of choosing a library that supports parallel processing and adaptive refinement effectively.

I want to start a project that requires parallel code for adaptive mesh refinement. I don't want to re-invent the wheel, and was hoping to leverage an open source library as a starting point. Does anyone have experience with any of these codes and could make a recommendation? At this point I am considering the following codes, but am open to others:

(1) Open Foam
(2) LLNL/SAMRAI
(3) LANL/CLAMR
(4) MIT SU2

I have some limited knowledge of OpenFOAM, which I think is a great platform as it allows lots of flexibility. You will find lots of information online on how adaptive meshing can be implemented in OpenFOAM.
