Distributed Immersed Boundary Simulation in Titanium
SIAM Journal on Scientific Computing, 2006 Summary: 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.

A comparative study of immersed-boundary interpolation methods for a flow around a stationary cylinder at low Reynolds number [PDF]
, 2013 The accuracy and computational efficiency of various interpolation methods for the implementation of non grid-confirming boundaries is assessed. The aim of the research is to select an interpolation method that is both efficient and sufficiently accurate

Moving immersed boundary method [PDF]
International Journal for Numerical Methods in Fluids, 2017 SummaryA novel implicit immersed boundary method of high accuracy and efficiency is presented for the simulation of incompressible viscous flow over complex stationary or moving solid boundaries. A boundary force is often introduced in many immersed boundary methods to mimic the presence of solid boundary, such that the overall simulation can be ...

From Immersed Boundary Method to Immersed Continuum Methods
International Journal for Multiscale Computational Engineering, 2006 The 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.

Pressure boundary conditions for immersed-boundary methods. [PDF]
J Comput Phys, 2023 Immersed boundary methods have seen an enormous increase in popularity over the past two decades, especially for problems involving complex moving/deforming boundaries. In most cases, the boundary conditions on the immersed body are enforced via forcing functions in the momentum equations, which in the case of fractional step methods may be problematic

Benchmarking the Immersed Boundary Method for Viscoelastic Flows. [PDF]
J Comput PhysWe present and analyze a series of benchmark tests regarding the application of the immersed boundary (IB) method to viscoelastic flows through and around non-trivial, stationary geometries. The IB method is widely used for the simulation of biological fluid dynamics and other modeling scenarios where a structure is immersed in a fluid. Although the IB

Immersions of surfaces with boundary into the plane [PDF]
Pacific Journal of Mathematics, 2003 Let \(M\) be a compact connected oriented surface with boundary. \textit{L. Kaufman} characterized all orientation preserving immersions of \(M\) into the plane up to image homotopy in [Illinois J. Math. 23, 684--665 (1978; Zbl 0425.57007)], where two orientation preserving immersions \(f\) and \(g\) of \(M\) into the plane are said to be image ...

The volume-filtering immersed boundary method
Journal of Computational Physics, 2023 We present a novel framework to deal with static and moving immersed boundaries (IB). In this strategy, called Volume-Filtering Immersed Boundary (VFIB) method, transport equations are derived by filtering the Navier-Stokes equations and accounting for stresses at the solid-fluid interface.
