n-chinese-remainders
chinese remainder theorem - progressive solving, n-soln, extras
"chinese remainder" solves a system of equations over modulus quickly. crtwo is an improvement to Mathematica's release. crtwo: solves Chinese Remainder a pair at a time, (uses gcd), yet is still fast. Which means crtwo, unlike text book soln, uses an algorithm to solve or fail one mod equation at a time. showing win or fail of each eqn and solving other sawtooth intersections is possible, due to that. -

CFD2D
The incompressible Navier-Stokes equations solver in 2D domains
CFD2D is open source software for Linux for solving the non-dimensionalized incompressible Navier-Stokes equations (NSE) inside an arbitrary two-dimensional domain inscribed in a unit square with Dirichlet and "do-nothing" boundary conditions. The space discretization is based on Finite Element Method (FEM) using an approximately uniform triangular mesh. The two choices of FE spaces are offered, these are of the so called MINI-element and of the Taylor-Hood element. -

...Karl |1|, using a discrete approach for the approximation of level-set based curve evolution (implicit active contours). This is a novel (2005) and fast algorithm without the need of solving partial differential equations (PDE) while preserving the advantages of level set methods, such as the automatic handling of topological changes. Considerable speedups (×100) have been demonstrated as compared to PDE-based narrow band level-set implementations.

Math Simulator
A simulation software for numerical techniques.
Math Simulator is a java-based application which simulates various mathematical techniques.It is extremely useful for the Engineering students and for professionals. Most importantly, unlike most others Math Simulator is an Application rather than a java - library. So, user is not required to have any computer background. A Unique feature of Math Simulator is that it allows you to save queries for later reference. Hence you can save the problems along with their results. -

Fast Solver for Potential and LFFFs
This is a fast solver for global potential field in the Solar Corona
This is a fast solver for computing the potential and linear force-free field (LFFF) above the full photosphere with the line-of-sight synoptic magnetogram as input. The global potential field and the LFFF are dealt with in an unified way by solving a three-dimensional Helmholtz equation in spherical shell and a two-dimensional Poisson equation on the photosphere. The solver is based on a combination of the spectral method and the finite-difference scheme. In longitude direction the equation is transformed into Fourier spectral space and the resulted 2D equations in r–θ plane for the Fourier coefficients are solved by finite difference in a direct way. ... -
