Internally, ANSYS FLUENT stores the computational mesh in meters, the SI unit of length. When mesh information is read into the solver, it is assumed that the mesh was generated in units of meters. If your mesh was created using a different unit of length (inches, feet, centimeters, etc.), you must scale the mesh to meters. To do this, you can select from a list of common units to convert the mesh or you can supply your own custom scale factors. Each node coordinate will be multiplied by the corresponding scale factor.
Scaling can also be used to change the physical size of the mesh. For instance, you could stretch the mesh in the direction by assigning a scale factor of 2 in the direction and 1 in the and directions. This would double the extent of the mesh in the direction. However, you should use anisotropic scaling with caution, since it will change the aspect ratios of the cells in your mesh.
In this tutorial tyou will learn how to scale the mesh using Ansys Fluent. Changing units in geometries is a very recurring error before starting the simulation. In this tutorial you can scale your mesh without modifying your geometry.

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. Unlike liquids, gases cannot form a free surface on their...
