Free surface is the surface of a fluid that is subject to zero parallel shear stress, such as the interface between two homogeneous fluids, for example, liquid water and the air in the Earth’s atmosphere.

Please add this setup about Initialization, right click on Flow Analysis > Insert > Global Initialization then double click on Global Initialization and modify as it appears in the image below.

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.

Thermodynamics is a branch of physics that deals with the energy and work of a system. Thermodynamics deals only with the large scale response of a system that we can observe and measure in experiments. In aerodynamics, we are most interested in the thermodynamics of propulsion systems and high speed flows.

A tetradecahedron is a polyhedron with 14 faces. There are numerous topologically distinct forms of a tetradecahedron, with many constructible entirely with regular polygon faces.

The Offset function allows you to create a set of lines and arcs that are offset by an equal distance from an existing set of “straight” lines and “circular” arcs. The original set of lines and arcs must be connected in a simple end-to-end fashion and can form either an open or closed profile.

The ANSYS DesignModeler application is designed to be used as a geometry editor of existing CAD models.

The Body Operation feature allows you to manipulate bodies. Any type of body can be used with body operations, regardless of whether it is active or frozen. However, point feature points (PF points), attached to the faces or edges of the selected bodies, are not affected by the body operation.
