An Immersed Interface Method for Discrete Surfaces

no code implementations17 Dec 2018 Ebrahim M. Kolahdouz, Amneet Pal Singh Bhalla, Brent A. Craven, Boyce E. Griffith

The immersed interface method(IIM) is an IB-like approach to FSI that sharply imposes stress jump conditions, enabling higher-order accuracy, but prior applications of the IIM have been largely restricted to methods that rely on smooth representations of the interface geometry.

Image-based immersed boundary model of the aortic root

no code implementations4 May 2017 Ali Hasan, Ebrahim M. Kolahdouz, Andinet Enquobahrie, Thomas G. Caranasos, John P. Vavalle, Boyce E. Griffith

Each year, approximately 300, 000 heart valve repair or replacement procedures are performed worldwide, including approximately 70, 000 aortic valve replacement surgeries in the United States alone.

An Immersed Boundary Method with Divergence-Free Velocity Interpolation and Force Spreading

1 code implementation25 Jan 2017 Yuanxun Bao, Aleksandar Donev, Boyce E. Griffith, David M. McQueen, Charles S. Peskin

The aim of this paper is to greatly reduce the volume error of the IB method by introducing velocity-interpolation and force-spreading schemes with the properties that the interpolated velocity field in which the structure moves is at least C1 and satisfies a continuous divergence-free condition, and that the force-spreading operator is the adjoint of the velocity-interpolation operator.
