Surface Slit
Use a Surface Slit plot to display a quantity that is the result of evaluating one expression on one side and another expression on the other side of a boundary in 3D (). When you add an expression to plot as a surface slit plot, and it is possible to evaluate it in the surrounding domains, you can use the up and down operators (see up and down) on each side of the boundary to evaluate an expression’s values on the upside and downside, respectively. For discontinuous expressions, the plot will show different values on the upside and downside without any use of the up and down operators.
Add Deformation, Filter, or Selection (Plot Attribute) subnodes as needed. Right-click a 3D Plot Group to add a Surface Slit plot from the More Plots submenu.

Expression on the Upside
See Expressions and Predefined Quantities for information about the settings for defining an expression to plot on the upside of the boundary.
Expression on the Downside
See Expressions and Predefined Quantities for information about the settings for defining another expression to plot on the downside of the boundary.
For exterior boundaries, the upside is the side toward the outside of the geometry. For interior boundaries, see Tangent and Normal Variables.
