Distributed Immersed Boundary Simulation in Titanium
SIAM Journal on Scientific Computing, 2006Summary: The immersed boundary method is a general numerical method for modeling elastic boundaries immersed within a viscous, incompressible fluid. It has been applied to several biological and engineering systems, including large-scale models of the heart and cochlea.

Immersed Boundary Projection Methods
2020Immersed boundary methods are an attractive alternative to body-fitted grids for complex geometries and fluid–structure interaction problems. The simplicity of the underlying Cartesian mesh allows for a number of useful conservation and stability properties to be embedded in the numerics, and for the resulting discrete equations to be solved ...

Boundary slip from the immersed boundary lattice Boltzmann models
Physical Review E, 2009We report an interesting and important observation of the velocity fields from immersed boundary lattice Boltzmann methods (IB-LBM). The computed velocity profiles can deviate from theoretical predictions greatly even for very simple flow situations, both in the immersed boundary layer and the bulk region.

A discontinuous‐Galerkin‐based immersed boundary method
International Journal for Numerical Methods in Engineering, 2008AbstractA numerical method to approximate partial differential equations on meshes that do not conform to the domain boundaries is introduced. The proposed method is conceptually simple and free of user‐defined parameters. Starting with a conforming finite element mesh, the key ingredient is to switch those elements intersected by the Dirichlet ...

From Immersed Boundary Method to Immersed Continuum Methods
International Journal for Multiscale Computational Engineering, 2006The objective of this paper is to present an overview of the newly proposed immersed continuum method in conjunction with the traditional treatment of fluidstructure interaction problems, the immersed boundary method, the extended immersed boundary method, the immersed finite element method, and the fictitious domain method.

Boundaries Immersed in a Scalar Quantum Field
Fortschritte der Physik/Progress of Physics, 1996We study the interaction between a scalar quantum field , and many different boundary configurations constructed from (parallel and orthogonal) thin planar surfaces on which is constrained to vanish, or to satisfy Neumann conditions. For most of these boundaries the Casimir problem has not previously been investigated.

In this paper, we report the extension of an earlier developed Direct Numerical Simulation (DNS) model to study coupled heat and mass transfer problems in particulate flows. The DNS model builds on an efficient ghost-cell based Immersed Boundary Method (IBM) which implicitly incorporates the boundary conditions into the discretized momentum, thermal ...

Immersed Boundary/Continuum Methods
2009In the study of biological systems, the coupling of fluid and solid/structure plays an important role. Traditionally, staggered iterations are used to link available finite element codes with computational fluid dynamics codes. Although this procedure is convenient, complex dynamical system behaviors often get lost in the process.
