CFD Toolbox: A Swiss Army Knife for Computational Fluid Dynamics Practitioners
CFD Toolbox is a free Chrome add-on developed by tomrobin.teschner. It is a collection of useful calculators specifically designed for Computational Fluid Dynamics (CFD) practitioners. The toolbox aims to provide a central place for common pre- and post-processing tasks in CFD simulations. With constant development, additional calculators are regularly added to enhance its functionality.
The current version of CFD Toolbox includes several calculators that cater to specific needs of CFD practitioners. The Y+ Calculator allows users to calculate the first cell height based on a target Y+ value and determine the number of layers required to cover the boundary layer. The Turbulence Boundary Conditions calculator calculates all the necessary input for inlet values of common turbulence (RANS) models.
Another useful calculator in the toolbox is the Grid Convergence Study, which calculates the Grid Convergence Index (GCI) for a series of three grids with respect to an integral flow quantity. This helps users assess the accuracy and consistency of their simulation results. Additionally, the CO2 Calculator enables users to calculate the amount of CO2 produced by a single CFD simulation and compare it to the equivalent CO2 emission of a car, providing a sense of scale.
The International Standard Atmosphere (ISA) Calculator is another valuable tool in the CFD Toolbox. It calculates properties in the atmosphere, such as temperature, density, pressure, speed of sound, and kinematic/dynamic viscosity. Users can input a reference temperature and height above mean sea level (MSL) to obtain the desired atmospheric properties.
CFD Toolbox is a comprehensive add-on that simplifies various aspects of CFD simulations. With its range of calculators, it serves as a valuable resource for CFD practitioners, offering convenience and efficiency in their daily workflow.
