This example illustrates face-fitting of a volume element which has
collapsed nodes (top two nodes). Figure 2 depicts the fitted mesh with
single version for the derivatives of the collapsed nodes. The fitted
mesh shown in the figure 3 has multiple versions for the derivatives of
the collpased nodes. Currently CMISS is capable of face-fitting in
volume meshes containing nodes collapsed at any xi location (xi1=0.0,
xi1=1.0 ... etc.) and in any xi directions.
Note how the derivatives of the collapsed nodes with multiple
versions are fixed in the *.ipfit files and see the note in the com
file.
