Detailed Description

An abstract class for defining a 2-dimensional hole.

We assume that the connectivity of the hole is implicit in the numbering of the points, controlled by segment_indices vector. The size of segment_indices is equal to the number of segments plus one. Each segment has segment_indices[i+1]-segment_indices[i] connected points, with node segment_indices[i] is connected to node segment_indices[i+1], node segment_indices[i+1] is connected to node segment_indices[i+2], etc, and the last node "wraps around" to connect back to node segment_indices[i].

Implemented in libMesh::TriangleInterface::ArbitraryHole, and libMesh::TriangleInterface::PolygonHole.

segment_indices()

virtual std::vector<unsigned int> libMesh::TriangleInterface::Hole::segment_indices ( ) const

inlinevirtual

Starting indices of points for a hole with multiple disconnected boundaries.

Reimplemented in libMesh::TriangleInterface::ArbitraryHole.
