Fosite is a generic framework for the numerical solution of hyperbolic conservation laws in generalized orthogonal coordinates. Its main purpose is the simulation of compressible flows in accretion disks. The underlying numerical solution method belongs to the family of unsplit conservative finite volume TVD schemes. The method is 2nd order accurate in space and uses high order Runge-Kutta and multistep schemes for time evolution. In addition to the pure advection code several source terms...

...News: V2.1 with many improvements released on 07/15/2016. Sources and binaries are available. RMG is a density functional theory (DFT) based electronic structure code that uses real space grids to represent wavefunctions, charge densities and ionic potentials. Designed for scaleability it has been run successfully on systems with thousands of nodes and hundreds of thousands of CPU cores. It is currently under active development and contributions are gladly accepted.

Construct2D is a grid generator designed to create 2D grids for CFD computations on airfoils. The grids are generated in Plot3D format. The only required input file is the set of coordinates defining the airfoil geometry, using the same format as XFoil, the popular vortex-panel code for airfoil analysis. Construct2D can create grids with O topology (recommended for airfoils with a blunt trailing edge) or C topology (recommended for airfoils with a sharp trailing edge). ...

vecds - Visual Editor of Crystal Defects - A QT and OSG application for visualization of atom-embedded grids.

PLEASE NOTE ORBKIT HAS BEEN MOVED TO https://github.com/orbkit/orbkit orbkit is a parallel Python program package for post-processing wave function data extracted from output files of MOLPRO (Molden File Format), TURBOMOLE (AOMix file format), GAMESS-US, PROAIMS/AIMPAC (wfn/wfx file format), and Gaussian (Output File and Formatted Checkpoint File) output files. Futhermore, an interface to cclib, a parser for quantum chemical logfiles, is provided. If you use orbkit in your work,...

Computational Fluid Dynamics (CFD) solver aimed to solve multi-physics problems on unstructured grids (inviscid Euler, Navier-Stokes flows, Heat transfer). F90 based. MPI, cgns, Metis libraries used.

...These require significant effort in practice to compute emissivities for given input spectra. To supplement these matrices I provide here a C++ class which reads the matrices, interpolates on user-defined particle and gamma-ray energy grids, and computes the gamma-ray emissivity either differential or in user-defined bands. A sample user program is provided which can be edited to provide the required functionality. See also http://sourceforge.net/projects/galprop, which includes more models.

A 2-D inviscid flow and adjoint solver on unstructured triangular grids. It makes use of a vertex-centroid finite volume scheme which is second order accurate. The adjoint solver is developed using the automatic differentiation tool called TAPENADE. Code has been moved to https://github.com/cpraveen/euler2d
