this is because in the current svn version I have replaced x[..] in
the python interface with x,y,z so that it is consistent with the
Matlab interface and the usual muparser expressions.

Dear Yves Renard,
that's strange. This part of
the code runs at my system without any problems. If I use y
instead of x[2] I get the error message "NameError: name 'y'
is not defined".
I'm using ubuntu 11.10 with
getfem++ 4.1.1.
Kind regards,
Radames

When
I run your program, I have a problem with the eval
methods :
mfpt.eval("c*(x[1]-r) * I",{'c':c, 'r':r_tube, 'I':I})
p_o = mfpo.eval("p(x[2]) * I",{'p':p_atm , 'I':I})
p_i = mfpi.eval("p(x[2]) * I",{'p':p_tube, 'I':I})
Normally, x[1] and x[2] are not defined. The available
coordinates are the scalar variables x, y and z.
But I have an error message ...
Yves.

Dear all,
my getfem++ model is killed with signal 9 and I've
no idea why.
I try to use gmsh and getfem++ to calculate the
deformation of a pressurized tube. I model the
tube as a thin walled cylinder with top and bottom
in gmsh. I use python as the interface to getfem++
to describe the high inside pressure, the lower
outside pressure, the asymmetric top pressure and
a diriclet bottom. When I run this programm it
starts, but it crashes without any hint why.
I tried this with different length of the
cylinder, with different thickness of the walls,
and with meshes of different granularity. The
result is always the same: the program is killed.
Only with a very small flat cylinder it succeeded,
but I'm interested in the behaviour of a long
tube-like cylinder. I've suspected the main
memory, but I've added plenty of virtual memory
without an observable change.
Can you give me any hints how to overcome the
problem or what I'm doing wrong?
Many thanks in
advance.
Kind regards,
Radames
