UPDATE: both files (.gmsh and .msh) are present, Popen() could not find
them though.
At line 226-229 in gmshMesh.py:
while True:
print ["gmsh", geoFile] + gmshFlags + ["-o", mshFile]
p = Popen(["gmsh", geoFile] + gmshFlags + ["-o",
mshFile],
stdout=PIPE)
the first argument comes out as :
['gmsh', <path to .gmsh>, '-2', '-nopopup', '-format', 'msh', '-o', <path to
.msh>]
Thanks in advance!

Hi everyone, I am experiencing /troubles /with the *fipy.Gmsh2D
function with* *string*-wise script *input* in the /circle diffusion
example/.
Please find the script in attachment (and note that I applied a little
trick <http://comments.gmane.org/gmane.comp.python.fipy/3725> to
circumvent the Gmsh version error). Running it gives me this error:
Traceback (most recent call last):

It seems something goes wrong in the /temporary file creation/ in the
*openMSHFile*()-function in *gmshMesh*.*py *since it /can not find the
file/ with *Popen*() at *line 227.
*If anyone could assist me with this it would be really great.
Thank you in advance!
