triangulation_order3_contour_test

triangulation_order3_contour_test, a MATLAB program which calls triangulation_order3_contour() to read datafiles describing a set of nodes, their triangulation, and the value of a scalar quantity at each node, and create a color contour plot of the scalar.

CHANNEL is a channel region 3 units wide and 1 unit high. A Stokes flow solver has computed the fluid velocity and pressure in the channel. The pressure is a scalar and can be plotted by this routine.

• channel_nodes.txt, a node file;
• channel_elements.txt, an element file;
• channel_values.txt, a value file;
• channel_contours.png, a PNG image of the interpolated contour plot of the data;

ELL is an L-shaped region.

• ell_nodes.txt, a node file;
• ell_elements.txt, an element file;
• ell_values.txt, a value file;
• ell_triangulation.png, a PNG image of the triangulation;
• ell_contours.png, a PNG image of the interpolated contour plot of the data;

ELL2 is the same as ELL, except we do not supply the elements. The program will work just the same, except it will compute triangular elements internally, and write a copy out as a file.
