**triangulation_l2q_test**,
a FORTRAN90 code which
calls triangulation_l2q(), which
reads information
describing a triangulation of a set of points using 3-node
("linear") triangles, and creates a 6-node ("quadratic")
triangulation.

triangulation_l2q, a FORTRAN90 code which reads information about a 3-node (linear) triangulation and creates data defining a corresponding 6-node (quadratic) triangulation;

- triangulation_l2q_test.sh, runs all the tests.
- triangulation_l2q_test.txt, the output file.

**EXAMPLE** is an example data set.

- example_nodes.txt, the nodes for the 3-node triangulation.
- example_elements.txt, the elements for the 3-node triangulation.
- example.png, a PNG image of the 3-node triangulation, created by TRIANGULATION_PLOT.
- example_l2q_nodes.txt, the nodes for the 6-node triangulation.
- example_l2q_elements.txt, the elements for the 6-node triangulation.
- example_l2q.png, a PNG image of the 6-node triangulation, created by TRIANGULATION_PLOT.
