End-to-end GPU acceleration of low-order-refined preconditioning for high-order finite element discretizations
Will Pazner, Tzanio Kolev, Jean-Sylvain Camier
In this paper, we present algorithms and implementations for the end-to-end GPU acceleration of matrix-free low-order-refined preconditioning of high-order finite element problems.…
High-Order Mesh Morphing for Boundary and Interface Fitting to Implicit Geometries
Jorge-Luis Barrera, Tzanio Kolev, Ketan Mittal +1
We propose a method that morphs high-orger meshes such that their boundaries and interfaces coincide/align with implicitly defined geometries. Our focus is particularly on the case…
Accelerating High-Order Mesh Optimization Using Finite Element Partial Assembly on GPUs
Jean-Sylvain Camier, Veselin Dobrev, Patrick Knupp +4
In this paper we present a new GPU-oriented mesh optimization method based on high-order finite elements. Our approach relies on node movement with fixed topology, through the Targ…
Low-order preconditioning for the high-order finite element de Rham complex
Will Pazner, Tzanio Kolev, Clark Dohrmann
In this paper we present a unified framework for constructing spectrally equivalent low-order-refined discretizations for the high-order finite element de Rham complex. This theory…
