Object describing various characteristics of a mesh.

`inherit 'layout pslg`

`method triangle : 'layout int_mat`

Array of triangle corners: for each triangle, give the 3 indices of its corners, followed by (the indices of) other nodes if the triangle represents a nonlinear element. Its size is `c * n`

(`fortran_layout`

) where `n > 0`

is the number of triangles and `c >= 3`

is the number of nodes.

`method neighbor : 'layout int_mat`

Array of triangle neighbors; 3 int per triangle. It is of size `3 * n`

(`fortran_layout`

) where `n`

is 0 (i.e., neighbouring information is not given) or the number of triangles. Negative entries must be skipped (boundary triangles have less than 3 neighbors).

`method edge : 'layout int_mat`

Array of edge endpoints; 2 int per edge. It is of size `2 * n`

(`fortran_layout`

) where `n > 0`

is the number of edges.

`method edge_marker : 'layout int_vec`

Array of edge markers. Edges inside the domain receive the marker `0`

. It must either be empty (meaning that the information is not provided) or it must be of size `n`

, where `n`

is the number of edges.
