fhhos4

fhhos4 (pronounce ‘phosphore’) stands for Fast HHO Solver for Research. It is an open-source code that solves diffusion problems with the Hybrid High-Order (HHO) discretizations.

Features:

• solves diffusion problems with piecewise constant tensors
• HHO and DG discretizations
• high-order solutions
• handles unstructured meshes
• binded to the GMSH mesher
• implements geometric and algebraic multigrid methods
• exports linear systems
• shared-memory parallelism
• many parameters (various choices of polynomial bases, multigrid cycles, smoothers, coarsening strategies…)
