PlaneDeletionGenerator

Removes elements lying 'above' the plane (in the direction of the normal).

Description

Allows for deletion of elements that lie on one side of a plane. The plane can be specified via a point and a vector that is normal to the plane. All elements whose centroids lie "above" (in the direction of the normal vector) the plane will be removed from the mesh.

An optional new_boundary parameter can also be specified which will make any newly-created free-surfaces have that boundary ID.
