A Nodal Jacobian Inverse Solver for Reduced Complexity Eit Reconstructions
Electrical impedance tomography (EIT) uses surface electrodes to make measurements from which an image of the conductivity distribution within some medium is calculated. Calculation of conductivity solutions requires inverting large linear systems that have to date restricted reconstructions to 2D or coarse 3D domains. This paper presents a Nodal Jacobian Inverse Solver that scales with the num...
متن کاملAn Approximate Jacobian Nonlinear Solver for Multiphase Flow and Transport
We present an approximate Jacobian approach for solving nonlinear, multiphase flow and transport problems in porous media. A backward Euler time discretization scheme is used; prior to spatial discretization with a lowest order mixed finite element method (MFEM). This results in a fully implicit nonlinear algebraic system of equations. Conventionally, an exact Jacobian construction is employed ...

15 صفحه اولA parallel Jacobian-free Newton-Krylov solver for a coupled sea ice-ocean model
The most common representation of sea ice dynamics in climate models assumes that sea ice is a quasi-continuous non-normal fluid with a viscousplastic rheology. This rheology leads to non-linear sea ice momentum equations that are notoriously difficult to solve. Recently a Jacobian-free NewtonKrylov (JFNK) solver was shown to solve the equations accurately at moderate costs. This solver is exte...
متن کاملCompactifying the Relative Jacobian over Families of Reduced Curves
0.1. Motivation and Goal. The problem of finding a natural relative compactification of the relative Jacobian over a family of curves has drawn a lot of attention since Igusa’s pioneering work [18] in the fifties. (In Subsect. 0.2 the reader will find a slightly more detailed account of this history, with references.) In the case where the curves in the family are geometrically integral, a very...
