An Embedded Boundary Scheme for Three-Dimensional Flow Over Terrain on a Staggered Mesh
Soonpil Kang, Ann S. Almgren, Mahesh Natarajan +5
This paper describes an embedded boundary (EB) approach for simulating three-dimensional fluid flow on a staggered mesh where the velocity components are defined on cell faces and…
A GPU-accelerated simulation of rapid intensification of a tropical cyclone with observed heating
Soonpil Kang, Francis X. Giraldo, Seth Camp
This paper presents a limited-area atmospheric simulation of a tropical cyclone accelerated using GPUs. The OpenACC directive-based programming model is used to port the atmospheri…
Multiscale Modeling Framework using Element-based Galerkin Methods for Moist Atmospheric Limited-Area Simulations
Soonpil Kang, James F. Kelly, Anthony P. Austin +1
This paper presents a multiscale modeling framework (MMF) to model moist atmospheric limited-area weather. The MMF resolves large-scale convection using a coarse grid while simulta…
A Performance Study of Horizontally Explicit Vertically Implicit (HEVI) Time-Integrators for Non-Hydrostatic Atmospheric Models
Francis X. Giraldo, Felipe Augusto Ventura de Braganca Alves, James F. Kelly +2
We conduct a thorough study of different forms of horizontally explicit and vertically implicit (HEVI) time-integration strategies for the compressible Euler equations on spherical…
