CFD Toolbox

A collection of useful Computational Fluid Dynamics (CFD) specific calculators and the swiss army knife for any CFD practitioner.

Each Computational Fluid Dynamics simulation requires an ever increasing number of input arguments to successfully set up simulations. The CFD Toolbox aims to provide a central place of calculators that can be used for common pre- and post-processing tasks. It is under constant development and additional calculators will be added from time to time. The current version supports the following calculators: - Y+ Calculator: Calculates the first cell height based on a target Y+ value, as well as the number of layers required to cover the boundary layer. - Turbulence Boundary Conditions: Calculates all required input for inlet values of common turbulence (RANS) models. - Grid Convergence Study: Calculates the Grid Convergence Index (GCI) for a series of 3 grids with respect to an integral flow quantity. - Parallel computations: Determine the optimum number of cores for parallel computations based on your solver. - CO2 Calculator: Calculate the amount of CO2 produced by a single CFD simulation and contrast that with an equivalent CO2 emission of a car for a sense of scale. - International Standard Atmosphere (ISA) Calculator: Based on a reference temperature and height above mean sea level (MSL), this tool will calculate properties in the atmosphere such as temperature, density, pressure, speed of sound and kinematic / dynamic viscosity.
