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 ...
