triangulation_refine_local, a MATLAB program which refines a triangulation locally; a single triangular element is replaced by four smaller triangles, and neighboring information is updated.

Source Code:

• triangulation_refine_local_test.m, calls all the tests;
• triangulation_refine_local_test.sh, runs all the tests;
• triangulation_refine_local_test.txt, the output file.

ELL3 is the original triangulation:

• ell3_nodes.txt the node coordinates.
• ell3_nodes.png an image of the nodes.
• ell3_elements.txt the elements.
• ell3_elements.png a PNG image of the elements.
• ell3_element_neighbors.txt, the neighbor triangles.
• ell3_element_neighbors.png, a PNG image of the neighbor information.

ELL3_REFINED is the triangulation after element 11 has been refined:

• ell3_refined_nodes.txt the node coordinates.
• ell3_refined_nodes.png an image of the nodes.
• ell3_refined_elements.txt the elements.
• ell3_refined_elements.png a PNG image of the elements.
• ell3_refined_element_neighbors.txt, the neighbor triangles.
• ell3_refined_element_neighbors.png, a PNG image of the neighbor information.
