- Improve evaluation of bond constraints in LAMMPS exports
- Add high-level method for transforming into "InterMol settings"
- Unclear how to split OpenMM torsion energies between propers and impropers
-
openmm.NonbondedForce
does not respectvdWHandler.cutoff
in the gas phase -
to_openmm_positions
has inconsistent return type -
to_openmm_positions
uses incorrect positions of isomorphic molecules - Add energy tests using SAMPL6 data set
- Document atom type "explosion" problem, de-duplication of GROMACS molecules
-
Do not require
ParameterHandler.combining_rules
when processing non-bonded handlers
