the same result...
Tomorrow I'll try a completely clean install of python, fipy and all
packages on another pc
Thanks

Make that branches/version-2_1 rather than trunk/.

An older version of fipy (tr...@3480, for example) gives,
In [1]: from fipy import *
m = CylindricalGrid1D(dx=(1.,2.))
/users/wd15/Documents/python/fipy/tr...@3480/fipy/viewers/gnuplotViewer/gnuplot1DViewer.py:76
is wrong.
I am doing some error?
Thanks

With any luck this has now been dealt with. Latest versions of
branches/version-2_1

Can you put together the simplest script possible that demonstrates
the problem and I'll try and debug it? Thanks

Edward, This may be to do with having a very small volume (or area or
line or point) for the inner most element of the domain. It should be
the same whether one is using a 1D or 2D mesh. Since you are getting
differences in the 1D and 2D case, it should be relatively easy to
debug and figure out

Hi,
I am trying to solve an eq of this type:
A(d phi/d t) = div (D grad phi) + q
in cylindrical coordinates. phi is the temperature. (A= 350, D= 05, q a
source(joule heating (which is as an hyperbola))
(BCs: Left - fixedflux =0, Right - FixedValue = 20.)
With 2D mesh
