triangulation_node_to_element_test

triangulation_node_to_element_test, a MATLAB program which calls triangulation_node_to_element() to read datafiles describing a set of nodes, their triangulation, and the value of one or more quantities at each node, and output a file that averages the quantities for each element. This operation in effect creates an "order1" finite element model of the data.

LAKE is a simulated lake with an island region.

• lake_nodes.txt, a node file;
• lake_elements.txt, an element file;
• lake_elements.pngt, an image of the lake elements;
• lake_values.txt, a value file;
• lake_element_values.txt, the node data, averaged over each element.
• lake_element_values.png, a 3D plot of the lake element values, as produced by triangulation_order1_display(). (We had to temporarily rename lake_element_values.txt to lake_values.txt to do this.)
