Novel permeability upscaling method using Fast Marching Method

Fuel, 2014
Abstract Despite computational advances, geo-cellular models are routinely upscaled for reservoir simulation purposes. Geo-cellular models typically incorporate small scale variations obtained from static data; whereas, simulation models capture dynamic data obtained from production of the field.

An adaptive domain-decomposition technique for parallelization of the fast marching method

Applied Mathematics and Computation, 2011
Abstract The fast marching method (FMM) is an efficient technique to solve numerically the Eikonal equation. The parallelization of the FMM is not easy because of its intrinsic sequential nature. In this paper we propose a novel approach to parallelize the FMM. It leads to an equation-dependent domain decomposition and it turns out to be particularly

On the use of fast marching methods for transcranial beam focusing

The Journal of the Acoustical Society of America, 2014
In this talk, we will present our recent studies on the use of fast marching methods for transcranial beam focusing. Three topics will be included: beam focusing for transcranial B-mode imaging, beam focusing for transcranial photoacoustic tomography, and beam focusing of a spherical array for therapy. To correct for the phase aberration from the skull,

Shared-memory parallelization of the fast marching method using an overlapping domain-decomposition approach

Spring Simulation Multiconference, 2016
The fast marching method is used to compute a monotone front propagation of anisotropic nature by solving the eikonal equation. Due to the sequential nature of the original algorithm, parallel approaches presented so far were unconvincing.

A Characteristics Driven Fast Marching Method for the Eikonal Equation

2008
We introduce a new Fast Marching method for the eikonal equation. The method is based on the informations driven by characteristics and it is an improvement with respect to the standard Fast Marching method since it accepts more than one node at every iteration using a dynamic condition.
