Use a Logical Expression node (
) to make a selection of geometric entities based on a logical expression in terms of other named selections.
Select the Level for the geometric entities:
Domain,
Boundary,
Edge (3D only), or
Point.
In the Logical expression field, enter a logical expression in terms of other named selections to define the resulting selection. You can use parentheses and the following Boolean operators:
||,
&&, and
! for logical or (union), logical and (intersection), and logical not (complement), respectively. For example, the logical expression
means the union of selections sel1 and
sel2 minus the selection
sel3, where
sel1,
sel2, and
sel3 are the tags of previously defined named selections.
