- cut_dataVector of Real values providing cut information
C++ Type:std::vector
Description:Vector of Real values providing cut information
RectangleCutUserObject
Creates a UserObject for planar cuts on 3D meshes for XFEM
The RectangleCutUserObject defines the boundary of a rectangular cut for XFEM to make on a 3 dimensional mesh. The cut_data parameter is a vector of length twelve that defines the x, y , and z Real values of the four vertices that form the rectangular cut. The object calculates the midpoint of the rectangular cut and normal, and includes logic to determine if a given point is located within the cut plane.
