I'm trying to run an MD simulation in PBC, using ChemSpider-trained network:
def EnAndForce(z_, x_, nreal_, DoForce = True):
mtmp = Mol(z_,x_)
en,f = manager.EvalBPDirectEEUpdateSinglePeriodic(mtmp, PARAMS["AN1_r_Rc"],
PARAMS["AN1_a_Rc"], PARAMS["EECutoffOff"], nreal_,True)
return en[0], f[0]
lat=Lattice(np.eye(3)*70) # 70 angstrom box
m.properties["Lattice"]=lat
PARAMS["MDThermostat"] = "Nose"
PARAMS["MDTemp"] = 300
PARAMS["MDdt"] = 0.1 # fs
PARAMS["RemoveInvariant"]=True
PARAMS["MDV0"] = "Random"
PARAMS["MDMaxStep"] = 10000
PF = PeriodicForce(m,np.eye(3)*70) #m.properties["Lattice"])
PF.BindForce(EnAndForce, 70.0)
PARAMS["MDTemp"] = 300.0
PARAMS["MDdt"] = 0.05 # In fs.
traj = PeriodicVelocityVerlet(PF,"sim_300K")
traj.Prop()
