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.
