In CFD-Post it may be necessary to define a new coordinate frame for certain quantitative operations, which are described in Function Calculator.
Note:
There are several ways to insert a coordinate frame:
From the menu bar, select Insert > Coordinate Frame.
From the toolbar, click the Coordinate Frame
icon.Depending on the context, you may be able to perform an insert from the shortcut menu in the tree view.
You cannot use a user-defined coordinate frame as part of a general CEL expression. For example,
radius = sqrt(x_myAxis^2 + y_myAxis^2), is not valid.
For information on how to define a coordinate frame, see Coordinate Frame Details.
