GiD_fWriteElementsBlock (array of connectivities)

int GiD_fWriteElementsBlock( GiD_FILE fd, int num_elements, GP_CONST int *connectivities );
int GiD_fWriteElementsIdBlock( GiD_FILE fd, int num_elements, GP_CONST int *list_ids, GP_CONST int *connectivities );

int GiD_fWriteElementsMatBlock( GiD_FILE fd, int num_elements, GP_CONST int *connectivities, GP_CONST int *lst_material_id );

int GiD_fWriteElementsIdMatBlock( GiD_FILE fd, int num_elements, GP_CONST int *list_ids, GP_CONST int *connectivities, GP_CONST int *lst_material_id );

Description:

Write the connectivities array of the elements of the current mesh. These functions include GiD_fBeginElements() and GiD_fEndElements(). All elements are of the same type EType as described in GiD_fBeginMesh, GiD_fBeginMeshColor

If GiD_fWriteElementsBlock() or GiD_fWriteElementsMatBlock() are used, i.e. no list of element's id’s are provided, then the element's id’s are assumed to be 1..num_elements .

If GiD_fWriteElementsBlock() or GiD_fWriteElementsIdBlock() are used, i.e. no list of element’s materials are provided, then the elements id's are assumed to be 0 .

Parameters:

list_ids is the array of element’s id's and expected to be num_elements in size.

list_material_id is the array of element's material's and expected to be num_elements in size.

connectivities is the array consecutive element’s connectivities of the num_elements, and it is expected to have num_elements * NNode doubles. Being Nnode the number of nodes per element as specified in GiD_fBeginMesh, GiD_fBeginMeshColor .

Example:
C/C++ as in testpost_fd.c :

    int ids[ NUM_ELEMS ];
    int connectivities[ NUM_ELEMS * 3 ];
    int mat_ids[ NUM_ELEMS ];
    for ( int i = 0; i < NUM_ELEMS; i++ ) {
      ids[ i ] = G_elems[ i ].id;
      connectivities[ i * 3 + 0 ] = G_elems[ i ].n1;
      connectivities[ i * 3 + 1 ] = G_elems[ i ].n2;
      connectivities[ i * 3 + 2 ] = G_elems[ i ].n3;
      mat_ids[ i ] = 2;
    }
    GiD_fWriteElementsIdMatBlock( fdm, NUM_ELEMS, ids, connectivities, mat_ids );
