示例1: excite_system
# 需要导入模块: from fidimag.micro import Sim [as 别名]
# 或者: from fidimag.micro.Sim import save_m [as 别名]
def excite_system(mesh, time=5, snaps=501):
# Specify the stt dynamics in the simulation
sim = Sim(mesh, name='dyn', driver='llg_stt')
# Set the simulation parameters
sim.driver.set_tols(rtol=1e-12, atol=1e-14)
sim.driver.alpha = 0.05
sim.gamma = 2.211e5
sim.Ms = 8.6e5
# Load the initial state from the npy file saved
# in the realxation
sim.set_m(np.load('m0.npy'))
# Add the energies
A = 1.3e-11
exch = UniformExchange(A=A)
sim.add(exch)
anis = UniaxialAnisotropy(5e4)
sim.add(anis)
# dmi = DMI(D=8e-4)
# sim.add(dmi)
# Set the current in the x direction, in A / m
# beta is the parameter in the STT torque
sim.driver.jx = -1e12
sim.driver.beta = 1
# The simulation will run for x ns and save
# 'snaps' snapshots of the system in the process
ts = np.linspace(0, time * 1e-9, snaps)
for t in ts:
print('time', t)
sim.driver.run_until(t)
sim.save_vtk()
sim.save_m()示例2:
# 需要导入模块: from fidimag.micro import Sim [as 别名]
# 或者: from fidimag.micro.Sim import save_m [as 别名]
ttime.set_text('Time: {:.4f} ns'.format(time * 1e9))
tenergy.set_text('Energy: {:.6e} ns'.format(sim.compute_energy()))
# fig.show()
fig.canvas.draw()
else:
# Fidimag automatically saves the last state
sim.do_precession = False
sim.relax(dt=1e-13, stopping_dmdt=args.stopping_dmdt,
