Example 232: Fitting a Temperature Field to 2 Meshes

Fits a scalar temperature field to 2 disjoint elements. The data is orthoganally projected onto the two elements. The field is the function x^2 + y^2 defined by the first element. The same field is replicated on the second element.

This example can also be visualised: This shows the fitted field on each of the surfaces. The gold spheres represent the data points. The comfile is draw.com

The comfile run by this example is as follows:

fem def coor 3,1
fem def base;r;bilinear;example


fem def node;r;square;example
fem def elem;r;square;example

fem def field;r;square;example
fem def elem;r;square;example field

fem def data;r;temp;example field
fem def xi;c closest
fem def xi;w;temp_data
fem export data;temp_data as temp_data error


fem def fit;r;square;example
fem fit field

fem export node;square as square
fem export elem;square as square

Additional testing commands:

fem li node
