+MARBLES (Multi-scale Adaptively Refined Boltzmann LatticE Solver) is a
+computational fluid dynamics solver that leverages the lattice
+Boltzmann method (LBM) and block-structured adaptive mesh refinement
+(AMR) to simulate flows in complex media. MARBLES supports various
+parallel decomposition strategies, including the use of the Message
+Passing Interface (MPI) and OpenMP threading. All major GPU
+architectures (e.g., Intel, AMD, NVIDIA) are supported through the use
+of performance portability functionalities implemented in AMReX. The
+MARBLES software is released in NREL Software Record `SWR-23-37
+<https://doi.org/10.11578/dc.20231009.2>`_ “MARBLES (Multi-scale
+Adaptively Refined Boltzmann LatticE Solver)”.
