Dear Lee-Ping. My idea is to simple simulate a cell using two point particles in order to have cell division. That means, should be exist a intracellular potential that push away the two point particles within the cell until some critical distance. I been thinking that is possible to do that using a...

Thank you for your swift response. Indeed, you have a damping force + a random force. This ensure you have momentum conservation on the system. The damping force and the random force are usually linked via the dissipation fluctuation theorem. In order to have the correct integrator you need to modif...

Hi! I am new in this stuff. But I would like to know if it possible to apply a DPD (Dissipative particle dynamics) thermostat using openMM. On the other hand, I am trying to simulate a system compose by a molecule with to atoms. The think is there are intra molecular forces and extra molecular force...
