Example 265: Xi calculations in a host mesh

This example calculates the xi locations inside a host mesh of data points which have been scaled in the x and y components by a factor of 2.2

Results can be viewed with the cmgui comfile draw.com. The purple lines represent the host mesh and the green lines the fitted mesh. The purple spheres correspond to the original data points, the green fitted positions the data points scaled in x and y by 2.2 and the red points the reconstructed xi positions

The comfile run by this example is as follows:

# Calculating Analytic xi positions in a square

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

#
# Export the geometry of the original host mesh
#
fem export node;orig as orig
fem export elem;orig as orig

Additional testing commands:

fem write matr;gk  mat gk  using fit
fem write matr;gkk mat gkk using fit
fem write matr;grr mat grr using fit



fem update nodes
fem li node

fem list data error


#
# Export the new geometry
#
fem export node;cust as cust offset 400
fem export elem;cust as cust offset_elem 400
fem export data;new_data as new_data offset 500

#
# Reconstruct the positions from the xi posistions 
#  - For testing
#
fem def data;c from_xi
fem export data;exp_data as exp_data offset 1000
