Mirror 2D and Mirror 3D
Use a Mirror 2D () data set to extend a solution defined on one side of an axis to the other side of the axis. This can be useful for visualization of a solution to an axisymmetric problem. Use a Mirror 3D () data set to extend a solution defined on one side of a plane to the other side of a plane. Both are selected from the More Data Sets submenu.
Go to Common Results Node Settings for links to information about these sections: Data, Axis Data (Mirror 2D), and Plane Data (Mirror 3D).
Generally, operations on vector quantities using the mirror data set work if you use the Mirror data set directly from the plot but do not work if you use it indirectly with another data set in between. For example, use a mirror of a cut data set operation order rather than a cut of a mirror.
Advanced
Select the Define variables check box to create a Positive side indicator variable. The default, mir1side, is 1 in the original domain and 0 in the mirror. Use the Positive side indicator variable in the Expression section of a plot Settings window to exclude quantities from the mirror side. Under Space variables, enter or edit the variable names for the mirrored coordinate system. Enter or edit the x, y, and z (Mirror 3D only) variable names in the respective fields. The default names are mir1x, mir1y, and mir1z, respectively.
