Example 223: Fibre fitting example

This problem involves fitting a fibre field to a set of measured fibre angles. The problem has 1 element with a bilinear basis (which is also used as the fibre field basis). 16 data points arranged in four rows of 4 data points are used to fit the field. The data fibre angles go up in steps of 20 degrees per row.

The comfile run by this example is as follows:
