PyAMG

PyAMG is a library of Algebraic Multigrid (AMG) solvers with a convenient Python interface. AMG is a multilevel technique for solving large-scale linear systems with optimal or near-optimal efficiency. Unlike geometric multigrid, AMG requires little or no geometric information about the ... [More] underlying problem and develops a sequence of coarser grids directly from the input matrix. This feature is especially important for problems discretized on unstructured meshes and irregular grids. PyAMG features implementations of several popular AMG methods: Ruge-Stuben (RS) or Classical AMG, AMG based on Smoothed Aggregation (SA), and Adaptive Smoothed Aggregation (aSA). [Less]

agg-mg

This code is part of a research project at the Federal University of Pernambuco (UFPE). The objective is to develop an agglomeration multigrid algorithm for convergence acceleration of porous media flow solvers using an Edge-Based Finite Volume Method. C++ is the language being used for its ... [More] development and it makes extensive use of the FMDB (www.scorec.rpi.edu/FMDB/) database for meshes. Author: Bruno Luna [Less]

speight-mathematica

Here is some code for various projects. Asset pricing with recursive utility. Portfolio optimization with recursive utility. Principal agent problems (dynamic optimal contracting with moral hazard). Multigrid calibration and estimation.

neopz

NeoPZ is an object oriented programming environment which implements hp adaptive finite element algorithms. The PZ classes can be used standalone but can also be linked with blas, boost, pthread, log4cxx and metis. The advanced finite element technologies implemented are : h and hp adaptivity for ... [More] one, two and three dimensional meshes the variational formulation of the conservation law is separated from the generation of the approximation space. Therefore NeoPZ can be used for virtually any system of differential equation Various storage patterns for the global stiffness matrix : full, banded, skyline, sparse, frontal Iterative solvers with configurable preconditioners Post processing interface to opendx and vtk [Less]
