OpenFOAM is the free, open source CFD software developed primarily by OpenCFD Ltd since 2004. It has a large user base across most areas of engineering and science, from both commercial and academic organisations.

During the late 1920s and into the 1930s, the NACA developed a series of thoroughly tested airfoils and devised a numerical designation for each airfoil — a four digit number that represented the airfoil section’s critical geometric properties.

Compressibility effects are encountered in gas flows at high velocity and/or in which there are large pressure variations. When the flow velocity approaches or exceeds the speed of sound of the gas or when the pressure change in the system ( $\Delta p /p$) is large, the variation of the gas density with pressure has a significant impact on the flow velocity, pressure, and temperature.

Ansys BladeModeler software is a specialized, easy-to-use tool for the rapid 3D design of rotating machinery components. Ansys BladeModeler is used to design axial, mixed-flow and radial blade components in applications such as pumps, compressors, fans, blowers, turbines, expanders, turbochargers, inducers and more.

The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA).

The Slice feature improves the usability of ANSYS DesignModeler as a tool to produce sweepable bodies for hex meshing and to assign different cross sections in a line body.

Some import types (ACIS and AutoCAD) allow you to specify the units of the imported model. Before clicking Generate, you may be able to change the model units from the Details View, depending on the type of import. Note that some model types store their units, so no Model Units property will appear when importing them.
