A Finite Volume Preserving Scheme on Nonuniform Meshes and for Multidimensional Coalescence

L. Forestier-Coste, S. Mancini
2012 SIAM Journal on Scientific Computing  
We validate the scheme considering some classical tests both in one and two dimensions and discuss its behavior when gelation occurs.  ...  The multidimensional numerical scheme described in [21] is also based on a finite volume method and on the conservative form (1.4) .  ...  In this section we explain how we handle the cells overlap, that is how we compute the term (j,k)∈S i . Let us write the finite volume discretization for (1.1).  ...

A Semi-Lagrangian Finite Volume Method for Newtonian Contraction Flows

T. N. Phillips, A. J. Williams
2001 SIAM Journal on Scientific Computing  
An interpolation procedure based on area-weighting is used for the convection part of the computation.  ...  It is the treatment of convection together with the positioning of the mesh points that distinguish one finite volume method from another.  ...  A grid is placed on the computational domain, and a control or finite volume is associated with each unknown on the grid.  ...

Donna A. Calhoun, Christiane Helzel
2010 SIAM Journal on Scientific Computing  
We present a second order, finite volume scheme for the constant-coefficient diffusion equation on curved, parametric surfaces.  ...  Our parabolic scheme should appeal to researchers in the fields of geophysical fluid dynamics, computational biology and any other discipline that requires the solution of parabolic equations on quadrilateral  ...  Compute α using (3.48) 6.

Study of Discrete Duality Finite Volume Schemes for the Peaceman Model

C. Chainais-Hillairet, S. Krell, A. Mouton
2013 SIAM Journal on Scientific Computing  
We focus here on the numerical approximation by some Discrete Duality Finite Volume methods.  ...  This system is made of two coupled equations: an anisotropic diffusion equation on the pressure and a convection-diffusion-dispersion equation on the concentration of invading fluid.  ...  Discretization on unstructured grids for inhomogeneous, anisotropic media.

Fast Finite Volume Simulation of 3D Electromagnetic Problems with Highly Discontinuous Coefficients

E. Haber, U. M. Ascher
2001 SIAM Journal on Scientific Computing  
Doug Oldenburg and Dave Moulton for fruitful discussions and an anonymous referee for valuable comments on the first two sections of our exposition.  ...  As in [17] , we employ a finite volume technique on a staggered grid, where J and A are located at the cell's faces, H is at the cell's edges, and φ and ψ are located at the cell's center.  ...  In [17] , we further addressed possible significant jumps in the conductivity while µ is assumed constant by employing a finite volume discretization on a staggered grid, akin to Yee's method with the  ...

A Fully Mass and Volume Conserving Implementation of a Characteristic Method for Transport Problems

Todd Arbogast, Chieh‐Sen Huang
2006 SIAM Journal on Scientific Computing  
We also present techniques that allow one to conservatively implement wells. The techniques are illustrated in four numerical examples.  ...  We present a simple modification to the characteristics-mixed method that conserves both mass and volume of the transported fluid regions.  ...  We finally describe our volume adjustment algorithm in §6.  ...

GPU-Based Volume Reconstruction from Very Few Arbitrarily Aligned X-Ray Images

Daniel Gross, Ulrich Heil, Ralf Schulze, Elmar Schoemer, Ulrich Schwanecke
2010 SIAM Journal on Scientific Computing  
Thereby, reconstruction time on an up-to-date GPU interfaced with an off-the-shelf personal computer is reduced to minutes. Volume sizes of up to 320 3 can be reconstructed within about five minutes.  ...  When computing the Reconstructions from geometrically perturbed data based on total variation minimization.  ...

Direct Inversion of the Three-Dimensional Pseudo-polar Fourier Transform

Amir Averbuch, Gil Shabat, Yoel Shkolnisky
2016 SIAM Journal on Scientific Computing  
The algorithm is based only on one-dimensional resampling operations and is shown to be significantly faster than existing iterative inversion algorithms.  ...  The convergence speed of these algorithms and their accuracy are difficult to control, as they depend both on the sampling geometry and on the unknown reconstructed object.  ...  Redistribution subject to SIAM license or copyright; see http://www.siam.org/journals/ojsa.php Next, we define the discrete time Fourier transform of an n × n × n volume I by where ω x , ω y , ω z ∈ [−  ...
