An example cyclohexane

This input is recommended as a standard test both of new programme versions and of new users. Do examine the various sections of the resulting output carefully. 

All interactions, one torsion per bond, L-J functions with eps and r, one molecule,check of coding only. 

Note that you may run more than one CPF calculation in the same EXEC, but that you have only one choice of parameters and coordinates. (Do not attempt to run more than one EXEC CPP in a Job.) 

0-C-C 100. 109. 109. gives the tetrahedral angle to machine precision this also
