Explore advanced techniques for integrating MFEM (Modular Finite Element Methods) with structured mesh libraries in this 27-minute conference talk from the 2025 MFEM Workshop. Learn how LLNL's Christopher Vogl addresses the traditional limitation that restricts scientific software libraries to either structured or unstructured mesh approaches by developing innovative coupling features within the MFEM library. Discover the implementation of field transfer capabilities between element-based adaptive mesh refinement (AMR) frameworks in MFEM and patch-based AMR frameworks used in structured mesh libraries. Understand the generalization of MFEM's 2:1 AMR capability to support N:1 refinement patterns commonly found in structured mesh libraries. Examine practical demonstrations showcasing successful coupling implementations between MFEM and both the PISALE library and the AMReX library, illustrating how these developments enable multiphysics applications to leverage the strengths of both meshing approaches without being constrained to a single methodology.
