### 2.9.1. Using a Profile From One Location at Another Location

There are a number of approaches that can be used to apply a profile from one location at another.

1. For locations that both have a surface normal vector of X, Y or Z, export the data as a 2D Profile (for example, for two boundaries with a normal in the Z direction, export X and Y profile data). The data from the first boundary can then be used at the second with no need for modifications to the data.

2. Create a custom coordinate frame so that the locations exported from one boundary will map correctly to a new boundary. Bear in mind that the coordinate frame you select will also be used by the solver to interpret the U, V, W Cartesian components you enter on the Boundary Details tab. Also bear in mind that any expression used to specify these quantities will be interpreted with x, y, z as being in the local coordinate frame, and all other variables as being in the global coordinate frame. For details, see Coordinate Frames in the CFX-Pre User's Guide. For details, see Coordinate Frames.

3. Edit the data in your profile file directly to map the locations from the first boundary to the second.

4. Edit the arguments in CFX-Pre to the U, V, W expressions. As an example, the following modification is permitted in CFX-Pre: `myprofile.Velocity u(x,y,(z + 1[m])).`
