ln in for loop - pikm57 - Jun-17-2017
Hi,
I m trying to solve PDE with finite elements method. Problem is, when I put the part, which has ln(x) in it, I get error. I tried np.log() and math.log() but no luck. Can someone help me?
T[0,:] = T_ok
T[:,0] = T_in
for t in range(Nt):
for z in range(1,Nz+1):
T[t+1,z] = T[t,z]-(v_avg*dt/dz)*(T[t,z]-T[t,z-1])-(U*2*dt*L/(r_1*dz))*(((T_in-T_h)-(T[t,z]-T_h))/(np.log((T_in-T_h)/(T[t,z]-T_h))))
T[t+1,Nz+1] = T[t+1,Nz]

would be nice to expalin what the problem was for the benefit of other members who may come here searching for solution

The problem was that some values in ln() were <0.... such a stupid mistake
