Scaling WaterLily.jl with MPI and an improved geometric multigrid solver
Bernat Font, Marin Lauber, Tzu-Yao Huang +1
We present recent performance-oriented developments in WaterLily, a scale-resolving incompressible flow solver written in pure Julia that runs seamlessly on CPUs and GPUs of any ve…
Linear Kelvin Wave Predictions in the Limit
Gabriel D Weymouth
Linear wave theory captures the essential physics of free-surface flows at a fraction of the computational cost of nonlinear and viscous methods, making it attractive for design, r…
Stability of Kirigami parachutes in effectively infinite numerical domains
Gabriel D. Weymouth, Marin Lauber
Kirigami, the art of cutting flat sheets into deployable 3D structures, has recently inspired a new class of parachutes which can deploy into a naturally stable inverted canopy. Ho…
Sharp-interface Simulations of Energetic Multiphase Flows with Large Density and Viscosity Ratios
Tzu-Yao Huang, Nicolas Valle, Artur K. Lidtke +2
Flows with high density ratios, such as wave breaking and air entrainment in maritime applications, remain challenging to simulate due to their energetic and strongly nonlinear nat…
Boundary layer flow dynamics of propulsive flapping foils with increasing Reynolds numbers
Andhini N. Zurman-Nasution, Gabriel D. Weymouth, Bharathram Ganapathisubramani
We study flapping foils at optimally propulsive Strouhal number with increasing chord-based Reynolds number at , , and to examine changes in their…
WaterLily.jl: A differentiable and backend-agnostic Julia solver for incompressible viscous flow around dynamic bodies
Gabriel D. Weymouth, Bernat Font
Integrating computational fluid dynamics (CFD) solvers into optimization and machine-learning frameworks is hampered by the rigidity of classic computational languages and the slow…
