Spheroidal harmonics for generalizing the morphological decomposition of closed parametric surfaces
Mahmoud Shaqfa, Wim M. van Rees
Spherical harmonics (SH) have been extensively used as a basis for analyzing the morphology of particles in granular mechanics. The use of SH is facilitated by mapping the particle…
A sharp immersed method for 2D flow-body interactions using the vorticity-velocity Navier-Stokes equations
Xinjie Ji, James Gabbard, Wim M. van Rees
Immersed methods discretize boundary conditions for complex geometries on background Cartesian grids. This makes such methods especially suitable for two-way coupled flow-body prob…
MURPHY -- A scalable multiresolution framework for scientific computing on 3D block-structured collocated grids
Thomas Gillis, Wim M. van Rees
We present the derivation, implementation, and analysis of a multiresolution adaptive grid framework for numerical simulations on octree-based 3D block-structured collocated grids…
An immersed interface method for the 2D vorticity-velocity Navier-Stokes equations with multiple bodies
James Gabbard, Thomas Gillis, Philippe Chatelain +1
We present an immersed interface method for the vorticity-velocity form of the 2D Navier Stokes equations that directly addresses challenges posed by multiply connected domains, no…
Coordinated Crawling via Reinforcement Learning
Shruti Mishra, Wim M. van Rees, L. Mahadevan
Rectilinear crawling locomotion is a primitive and common mode of locomotion in slender, soft-bodied animals. It requires coordinated contractions that propagate along a body that…
Synchronised Swimming of Two Fish
Guido Novati, Siddhartha Verma, Dmitry Alexeev +3
We study the fluid dynamics of two fish-like bodies with synchronised swimming patterns. Our studies are based on two-dimensional simulations of viscous incompressible flows. We di…
