After a few years off, the North American High Order Methods Conference (NAHOMCon) returned on July 18-19 in San Diego. NAHOMCon provides a North American forum for computational scientists, mathematicians, scientists, and engineers to share ideas and techniques on, and further the state of the art of, high order methods for the solution of partial differential equations with applications to a broad range of scientific and engineering applications. The DOE co-design Center for Efficient Exascale Discretizations (CEED) participates in this conference. CEED is a partnership between two U.S. DOE laboratories (Livermore & Argonne) and five universities in support of the Exascale Computing Project.

The NAHOMCon22 program featured several LLNL speakers, whose GitHub profiles and abstracts are linked here:

• Will Pazner – Low-order tools for high-order finite elements
• Yohann Dudouit – Matrix-free nonconforming high-order Discontinuous Galerkin methods on GPU architectures with MFEM
• Vladimir Tomov – Multimaterial ALE remap with interface sharpening using high-order finite elements
• Ketan Mittal – Optimization, adaptivity, and surface fitting of high-order meshes
