phi-FD, a second order finite difference scheme for geometries defined by a level-set function: the Neumann case
Michel Duprez, Vanessa Lleras, Alexei Lozinski +2
We extend the phi-FD finite-difference scheme, which handles domains described by a level-set function on a Cartesian grid, to Neumann boundary conditions. The condition is relaxed…
Assessment of a Threshold Method for Computing Activation Maps from Reconstructed Transmembrane Voltages
Emma Lagracie, Lisl Weynans, Yves Coudière
Electrocardiographic imaging non-invasively reconstructs activation maps of the heart from temporal body surface potential maps by post-processing solutions of an inverse problem.…
Comparison of Two Formulations for Computing Body Surface Potential Maps
Emma Lagracie, Lisl Weynans, Yves Coudière
In order to establish a link between the activation map and the body surface signals, we want to compute body potentials from activation maps and a frontlike approximation of the a…
A numerical method for wave-structure interactions in the Boussinesq regime
Geoffrey Beck, David Lannes, Lisl Weynans
The goal of this work is to study waves interacting with partially immersed objects allowed to move freely in the vertical direction, and in a regime in which the propagation of th…
Immersed Boundary Method for the Complete Electrode Model in Electrical Impedance Tomography
Jérémi Dardé, Niami Nasr, Lisl Weynans
We propose an immersed boundary scheme for the numerical resolution of the Complete Electrode Model in Electrical Impedance Tomography, that we use as a main ingredient in the reso…
Generating boundary conditions for a Boussinesq system
David Lannes, Lisl Weynans
We present a new method for the numerical implementation of generating boundary conditions for a one dimensional Boussinesq system. This method is based on a reformulation of the e…
