Detailed Description

template<int dim>
class ryujin::CutCellDecomposition< dim >

A helper class that creates a triangulation from the cells of a triangulation aligned with an elevation profile (see MeshAlignment) that lie above the profile, so that the profile becomes its bottom boundary. After the alignment a cell is classified by the states of its vertices:

A cell without a vertex above the profile is dropped.
A cut cell has a unique above vertex and, at the opposite corner, a below vertex. The other two vertices lie on the profile and the cell is replaced by the triangle spanned by the above vertex and the two on-vertices.
A cell with three vertices on the profile (a corner captured by MeshAlignment) is replaced by the same triangle if the triangle of the three on-vertices lies below the profile.
All other cells are kept.

The boundary ids of the original mesh are preserved and every new boundary face is assigned the given profile boundary id.

A serial triangulation creates a serial triangulation, a parallel::distributed::Triangulation creates a parallel::fullydistributed::Triangulation on the same communicator. Every element is owned by the owner of its cell and the result does not depend on the number of MPI ranks.

Note: Only implemented in 2D.

Create triangulation from the cells of the aligned triangulation temporary above the profile. height is a callable taking a Point<dim> and returning the height of the profile at the horizontal position of the point.
