You can "move'' the grid by applying prescribed offsets to the Cartesian coordinates of all the nodes in the grid. This would be necessary for a rotating problem if the grid were set up with the axis of rotation not passing through the origin, or for an axisymmetric problem if the grid were set up with the axis of rotation not coinciding with the 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 axis.
You can translate grid points in FLUENT using the Translate Grid panel (Figure 6.8.11).
Using the Translate Grid Panel
The procedure for translating the grid is as follows:
