Geometric multigrid for an implicit-time immersed boundary method
Robert D. Guy, Bobby Philip, Boyce E. Griffith
The immersed boundary (IB) method is an approach to fluid-structure interaction that uses Lagrangian variables to describe the structure and Eulerian variables to describe the flui…
Efficient Variable-Coefficient Finite-Volume Stokes Solvers
M. Cai, A. J. Nonaka, J. B. Bell +2
We investigate several robust preconditioners for solving the saddle-point linear systems that arise from spatial discretization of unsteady and steady variable-coefficient Stokes…
A Minimally-Resolved Immersed Boundary Model for Reaction-Diffusion Problems
A. Pal Singh Bhalla, B. E. Griffith, N. A. Patankar +1
We develop an immersed-boundary approach to modeling reaction-diffusion processes in dispersions of reactive spherical particles, from the diffusion-limited to the reaction-limited…
