import numpy as np
import matplotlib.pyplot as plt    
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.animation as animation

#Define x,y vectors and meshgrid with function u on it

x = np.arange(0,10,0.1)

u = np.sin(X + Y)

#Create a figure and an axis object for the surface
#(which by the way is not initialized, because I don't know were to)

fig = plt.figure()
ax = fig.add_subplot(111,projection='3d')

#Define a kind-of animation function, imitating what I …
