Mirror 2D and Mirror 3D
Use a Mirror 2D () dataset 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 () dataset to extend a solution defined on one side of a plane to the other side of a plane. They are selected from the More 2D Datasets and More 3D Datasets submenus.
Go to Common Results Node Settings for links to information about these sections: Data, Axis Data (Mirror 2D), and Plane Data (Mirror 3D).

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.
From the Vector transformation list, choose Symmetric (the default) or Antisymmetric. The symmetric transformation negates the vector component orthogonal to the symmetry axis or plane. The antisymmetric transform negates the vector components parallel to the symmetry axis or plane. The latter option can be useful for visualizing models with odd symmetry.
If desired, select the Remove elements on the symmetry plane check box to not include and elements that lie on the symmetry plane.
