License: GPL tochnog is a finite element analysis program. http://info.uibk.ac.at/c/c8/c813/tn_release/tnhome.html The author calls the executable 'tn' . I should probably change this to 'tochnog' or 'tng' or something. John John Lapeyre <lapeyre@physics.arizona.edu> Tucson,AZ http://www.physics.arizona.edu/~lapeyre
