Hi there,
I am a new python user.
I have a question regarding do loop.....
This is a simple program that I have written:
-----------------
N=10
h=10.0 # [micrometer]
z=-200.0 # [micrometer]
num = 0.05 #m**2/s
dz = 1.0
nuh=[]
tmax=3600
dt=20.
nu=[]height = arange(z*dz,0,dz)
outfile=open('nu.dat','w')
outfile.write('height, nu, nuh')
for z,when in enumerate(height):
for h in range(10):
for N in range(10):
for z in range((N-z)+(N-h)):
nuh.append(0.01 * exp(-0.05*(z+200.0))*dz) #turbulence
diffusivity m**2/s
nu.append(num + nuh[z])
-----------------------
What I like to do with this program is do loop like the fortran
version of as follows:
do i = 2, N
z(i) = z(i-1) +h(i-1)
end do
write(0,*) 'z ', z(1:N)
write(0,*) 'when ', 'nu ','Conc '
do i= 1, N
nuh(i)= 0.01d0*exp(-0.005d2*(z(i)+200)) ! turbulence diffusivity m**2/s
nu(i)= num(1) + nuh(i)
end do
----------
My problem is I am notable have the curve in the output plot as I have
as a result of FORTRAN program. What happens is just having a
straight line....!
the whole problem is in z part, which is supposed to be changed and i
do not see it!
So, would it be possible to take a look at it please. any suggestion
would greatly appreciated.
Thank you,
Sue
