Example #1

    return 2 * u


T = 10 * pi  # simulate for t in [0,T]
dt = 0.2
N = int(round(T / dt))

F = zeros(t.size)
I = 1
V = 0
m = 2
b = 0.2
u = solver_linear_damping(I, V, m, b, s, F, t)

from matplotlib.pyplot import *

savefig('tmp.pdf')  # save plot to PDF file
savefig('tmp.png')  # save plot to PNG file
show()
# End solver_linear_damping

import numpy as np
from numpy import sin, pi  # for nice math
from solver import solver


def F(t):

Example #2
