6.8.12 Translating the Mesh

You can "move'' the mesh by applying prescribed offsets to the Cartesian coordinates of all the nodes in the mesh. This would be necessary for a rotating problem if the mesh were set up with the axis of rotation not passing through the origin, or for an axisymmetric problem if the mesh were set up with the axis of rotation not coinciding with the $x$ axis. It is also useful if, for example, you want to move the origin to a particular point on an object (such as the leading edge of a flat plate) to make an XY plot have the desired distances on the $x$ axis.

You can translate mesh points in ANSYS FLUENT using the Translate Mesh dialog box (Figure  6.8.11).

Using the Translate Mesh Dialog Box

The procedure for translating the mesh is as follows:

1.   Enter the desired translations in the $x$, $y$, and (for 3D) $z$ directions (i.e., the desired delta in the axes) in the X, Y, and Z text-entry boxes in the Translation Offsets group box. You can specify positive or negative real numbers in the current unit of length.

2.   Click the Translate button and redisplay the mesh. The Domain Extents will be updated to display the new extents of the translated mesh. (Note that the Domain Extents are purely informational; you cannot edit them manually.)
