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 heat transfer and the effect of surface roughness on near wall flow are considered by this program, it can be used for engineering calculation of the friction drag and heat transfer coefficients on airfoil surface. ... -

datasw
datasw, a tool for rapid processing of HPLC-SAXS data.
Small-angle X-ray scattering (SAXS) in solution is a common low-resolution method which can efficiently complement high-resolution information obtained by crystallography or NMR. Sample monodispersity is key to reliable SAXS data interpretation and model building. Beamline setups with inline high-performance liquid chromatography (HPLC) are particularly useful for accurate profiling of heterogeneous samples. The program DATASW performs averaging of individual data frames from HPLC-SAXS experiment using a sliding window of a user-specified size, calculates overall parameters (I(0), Rg, Dmax and MW) and predicts the folding state (folded/unfolded) of the sample. ... -

easyNRG
A simple MATLAB implementation of Wilsons NRG-method
At the moment this code can calculate free electron gas and the SIAM (single-impurity-anderson-model) In this version, the only thing computed by the code is the energy flow. There is no calculation for any thermodynamic quantaties. The implementation is very slow and rather for educational purposes to get an idea of the NRG-method. For example: it is not considered, that only matrix elements between states, whos occupation number differs by one and S_z differs by 1/2. There is only implicit parallelisation implemented by vectorizing the time consuming parts of the code.

Samples of calculations and standard comparison with publications using the library will be given for demonstration of the usage. Interface to some commonly used software, such as Lumerical FDTD Solutions, will also be developed in the project. This project is titled under nanophotonics, quantum optics, nano-optics, computational physics and physics.
