Fosite - advection problem solver
numerical simulation code for solving transport equations in 1D/2D/3D
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 have been implemented including viscous diffusion and gravitational acceleration. ... -

ransfoil
console to calculate airflow around an airfoil based on RANS approach
RANSFOIL is a console program to calculate airflow field around an isolated airfoil in low-speed, subsonic, transonic or supersonic regime by numerically solving the Reynolds averaged Navier-Stokes (RANS) equations using mature computational fluid dynamics (CFD) method. As postprocess results, the aerodynamic parameters of the airfoil, e.g., lift coefficient and drag coefficient, can be integrated from the airflow distribution near wall boundary. In addition, the coupling between airflow and... -

Correlated random noise generator
C++library to generate a random noise with isotropic correlation.
It is a C++ library that implements a Fourier Filtering Method (FFM) to generate Gaussian random noise with any correlation with the only requirement of isotropy in both one and two dimensions. Unlike previous FFM that are only suitable to generate disorders whose correlation Fourier Transform (FT) has an analytical expression, it should be enlightened that the present method works with any isotropic and finite correlation, even its analytic FT does not exist. -
