You can easily export data such as displacements, stress, strain, etc. from 3DEC for specified profiles. For example:
program log on
program log-file ‘displacement.dat’
block list profile displacement begin 0 0 0 end 10 0 0 segments 10
program log off
This will export the displacement values along a line from x,y,z = 0,0,0 to 10,0,0 to a file called displacement.dat. You can also do this in FLAC3D.
