Using the web server on multicyclic molecules, the OpenMM .xml file contains some torsions that have all of the force constants = 0.00000.
A simple example is DABCO (smiles=C1CN2CCN1CC2) for which the output contains lines including:

For some other molecules, both Proper and Improper torsions like this appear.
Are these non-functional torsions evidence of
