Split_Triangle()

static int Kratos::TriangleSplit::Split_Triangle ( const int  edges[3], int  t[12], int *  nel, int *  splitted_edges, int *  nint  )

inlinestatic

Utility to split triangles.

Parameters

edges	--> (input) int c array of size 3
t	--> (output) int c array of size 12 (3*4)
nel	--> (output) number of elements in the subdivision
splitted_edges	--> (output) provides the number of splitted edges
nint	--> (output) internal node (not needed for triangles)

Returns

1->splitting needed 0-->no splitting needed

TriangleGetNewConnectivityGID()

static void Kratos::TriangleSplit::TriangleGetNewConnectivityGID ( const int  triangle_index, const int  t[12], const int  aux_ids[6], int *  id0, int *  id1, int *  id2  )

inlinestatic

utility function to get the global ids for the new triangles to be generated

Parameters

triangle_index	--> the index of the new triangle to be generated (Should be less than the number nel provided by Split_Triangle)
t	--> integer array provided by Split_Triangle
aux_ids	--> array used in constructing the edge_ids (contains the Global Ids of the new nodes)
id0	--> Global ID of node0 of the new triangle
id1	--> Global ID of node1 of the new triangle
id2	--> Global ID of node2 of the new triangle

TriangleSplitMode()

static void Kratos::TriangleSplit::TriangleSplitMode ( const int  aux_ids[6], int  edge_ids[3]  )

inlinestatic

this function computes the splitting mode for the triangle

Parameters

aux_ids

contains a vector with the input Ids, organized as follows: aux_ids[0] = id of FIRST node of the original triangle aux_ids[1] = id of SECOND node of the original triangle aux_ids[2] = id of THIRD node of the original triangle aux_ids[4] = id of new node to be used for the edge 01 (-1 if edge not to be splitted) aux_ids[5] = id of new node to be used for the edge 12 (-1 if edge not to be splitted) aux_ids[6] = id of new node to be used for the edge 20 (-1 if edge not to be splitted) given this data it fills an auxiliary vector of size 3 that will be used in the splitting

edge_ids

this is an auxiliary array with the local numbering. It is necessary for the split_triangle function
