...Its core algorithm of the simulation process refers to Robert Bridson's Fluid Simulation for Computer Graphics. It uses the numerical solution of Navier-Stokes equations to predict the density and velocity distribution of particles in each frame displayed in the OpenGL widget of Qt. There are two resolution options for users: 64 x 64 and 128 x 128. Users can also change display mode between density and velocity in 7 colors.

HYDRA is an VBA/EXCEL program for pipe network analysis of large solar thermal plants with collector areas of several thousands of square meters. - Hydraulic solar circuits can be modelled in detail. The main capabilities are: - Stationary flow-, temperature- and pressure distribution of large collector fields are calculated under arbitrary boundary conditions - cost-effective pipe routing and pipe dimensioning - automatic generation of diagrams for documentation - Dimensioning of Drainback systems with atmospheric storage tank, including the following tasks: - Pipe dimensioning for proper venting - Dimensioning of overflow valve - Proof of dissipation capability by simulation of steam range - Dimensioning overflow valve

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. RANSFOIL reads coordinates data from a 1D XYZ file which describes the grid points or control points on airfoil as only input, then outputs grid and solution files in 2D PLOT3D format to record grid coordinates and airflow data and a report file to show aerodynamic parameters.

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). Now available in...
