I am attaching the *.geo file.

I cannot run the script without the mesh .geo file, but anyway, a few remarks:

- the press_load Function instance is not used anywhere, do something like:

    functions = Functions([press_load])
    ...
    pb = Problem('elasticity', equations=eqs, nls=nls, ls=ls, functions=functions)

    - then the function will be available for equations etc.
(Problem.time_update() also can take 'functions' argument.)

- line 338: use get_mat instead of get_mat1

Could you send also the geometry file, so that I could run it?

r.
