Example 263: Find Xi coords of region 2 nodes within region 1 host mesh

This example uses the Xi coords of a set of 3D points (in face.ipxi - created by example 261) together with their target locations (in face_target.ipdata) to fit the nodes of a 4-element 18-node bicubic-linear host mesh. Distortion of the host mesh serves to match To view the host mesh and source data and target data, run the CMGUI comfile view.com

The comfile run by this example is as follows:

fem de coor;r;test
fem de regi;r;test               #reads in 2 regions
fem de base;r;test               #trilinear and bilinear basis functions


#
# Read in the host and slave meshes
#
fem de node;r;host reg 1
fem de elem;r;host reg 1
fem de node;r;slave reg 2
fem de elem;r;slave reg 2

#
# Export the host and slave meshes to cmgui
#
fem export node;host as host reg 1
fem export elem;host as host reg 1
fem export node;slave as slave reg 2
fem export elem;slave as slave reg 2


fem de wind
fem dr line reg all
fem dr node reg all

#
# Calculate the xi positions of the slave in the host mesh
#
fem de xi;c nodes contain of 2 in 1
fem li xi node
fem def xi;w;slave node reg 2
