Thanks for your suggestions. Its working now.
I don't know what the problem was in the first time.
How can I solve an ODE like ((D^2)+D)y=0 with BC: y(0)=3 and y(pi/2)=3
I have written this code, but I am not sure whether my representation of the
equation is correct or not and that is why I am not getting correct answer.
--------------------------------- Code--------------------------------------
import math
from fipy.meshes.grid1D import Grid1D
m = Grid1D(nx=50, dx=math.pi/100)
from fipy.variables.cellVariable import CellVariable
phi = CellVariable(name="solution variable",
mesh=m,
value=0)
valueleft=3
valueright=3
from fipy.boundaryConditions.fixedValue import FixedValue
BCs = (FixedValue(faces=m.getFacesRight(), value=valueright),
FixedValue(faces=m.getFacesLeft(), value=valueleft))
from fipy.terms.explicitDiffusionTerm import ExplicitDiffusionTerm
eqX = phi == ExplicitDiffusionTerm(coeff=1)
----------------------------------End of
Code-------------------------------------
I am not getting any errors in this code.
Thank you,
Amit

>>> from fipy import *

start a new python prompt and try
>>> from fipy.meshes.grid1D import Grid1D
>>> m = Grid1D(nx=2)
Do either of those work?

This is working fine(from fipy import *). It is not giving any errors.

What happens when you open up a python prompt and type
>>> from fipy import *

Hi,
I am getting an error in the line: "from fipy.meshes.grid1D import Grid1D",
which says:
ImportError: No module named fipy.meshes.grid1D
Importing only fipy also gives a similar error.
I have Python2.4.4, numpy, matplotlib and fipy installed on my computer.
Can anyone help me what might be causing this problem?
Thank you,
Amit
