Detailed Description
DEFINITION OF GEOMETRICAL CELLS (for meshes)
Choral constants for cells: CELL_xxx, see the list.
Geometrical cells composing meshes are described here.
DEFINITIONS
- Cell: a cell is a geometrical element (or control volume), for instance a tetrahedron or a triangle.
- A cell can be of dimension 0 to 3.
- A cell is always considered as embedded in \( \R^3\).
- A cell can be curved (hypergeometrical element).
- Node: a cell is defined with a set of ordered nodes.
- A node is a point in \(\R^3\).
- For instance a parabolic triangle has 6 nodes:
its 3 vertexes and the three midpoints od its edges.
- Vertex: a vertex of a cell.
- A cell of type CELL_xxx has \( n\) = CELL_NBVTX(CELL_xxx) vertexes, they are ordered.
- A vertex is always a node, but a node is not a vertex in general.
- convention for the ordering of cell nodes:
nodes \(1 \dots n\) are the cell vertexes with the same ordering. - A vertex is a geometrical cell of dimension 0.
- A cell of dimension 0 has 1 vertex: itself
- Edge: edge of a cell (dimension \( \ge 1\)).
- Edges can be curved: a curved cell has curved edges.
- An edge is a cell of dimension 1.
- A cell of dimension 1 has 1 edge: itself.
- Face: face of a cell (dimension \( \ge 2\)).
- Faces can be curved: a curved cell has curved faces.
- A face is a cell of dimension 2.
- A cell of dimension 2 has 1 face: itself.
- Reference cell: A cell is defined with a reference cell and a geometrical transformation.
- Geometrical transformation are defined in geotsf_mod.
- A reference cell is straight (not curved): a line segment, a triangle...
- The reference cell associated to a cell is referred to as the cell geometry in the library choral.
DESCRIPTION: cells are described by
- several integer constants (see the list) such as CELL_MAX NBVTX
- these constants have to be updated when adding a new cell type.
- a series of arrays (see the list) such as CELL_NBVTX:
- for a triangle cell (with type CELL_TRG), its number of vertexes is CELL_NBVTX(CELL_TRG)
- these arrays are initiated with call cell_init()
- for a triangle cell (with type CELL_TRG), its number of vertexes is
