LineSegmentCutSetUserObject

Creates a UserObject for a line segment cut on 2D meshes for XFEM

Overview

The LineSegmentCutSetUserObject defines a set of line segment cuts for XFEM to make on a 2 dimensional mesh. The cut_data parameter consists of entries each with a length of six Real values (the entries are not separate but rather the length of the cut_data vector must be a multiple of six). Each set of six values in cut_data prescribes a line segment cut: start point x, start point y, end point x, end point y, start cut time, end cut time. The object checks to ensure that the length of cut_data is a multiple of six. Provided that the start cut time and end cut time values are different, the cut will lengthen by at each timestep from start cut time until the specified end cut time. As in the LineSegmentCutUserObject, scaling and translation are available via optional parameters and apply to all applicable components of cut_data.
