Writting an amber force field

User discussions

Hi,

I am developing an amber force field for a branched polymer, but so far it did not work.

I am looking for any source helping me to understand <HarmonicBondForce>,

<HarmonicAngleForce> and <PeriodicTorsionForce>.

Best,

Elsaid

You’re on the wrong forum. You’re using OpenMM, not GROMACS.

The energy terms are clearly from OpenMM because GROMACS uses different names. You need to talk with their community via their forum if you need help.
