Example 261: Find Xi coords of source dataset within host mesh

This example finds the Xi coords of a set of 3D points (in face_source.ipdata) relative to a 4-element 18-node bicubic-linear host mesh. The Xi-coords are output in face.ipxi. To view the host mesh and source data, run the CMGUI comfile view.com

The comfile run by this example is as follows:

#Find Xi locations within 4 element bicubic-linear host mesh.
#Read host mesh 
fem de coor;r;host;example          #3D r.c. coords
fem de base;r;host;example          #bicubic-linear etc
fem de node;r;host;example          #18 nodes in host mesh        
fem de elem;r;host;example          #4 elements in host mesh
#Write host mesh to .exnode & .exelem files
fem ex node;host as host
fem ex elem;host as host
#Read source data 
fem de data;r;face_source;example 
fem ex data;face_source as data           
#Calculate face Xi coords within the host & output face.ipxi
fem de xi;c contain         #find Xi's of source data
fem de xi;w;face            #write data pt Xi's to face.ipxi 
fem quit
