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

Betreff: Re: [Getfem-users] python getfem++ is killed
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
