Hi Kent, thank you. Would you be kind enough to tell me how to install this? I downloaded and unpacked php-crypt-cbc-1.0.0.1 and I'm afraid I don't quite know what to do with it now. I apologize for my NOOB(iness)! I am running on the latest version of Ubuntu.

do
   bzr branch lp:cbc.solve

OK that appeared to work fine, but now when I try to run the twist hyperelastic problem (http://harishnarayanan.org/research/automated-mechanics/) i get this:

scottr99@scottr99-HP-Pavilion-dm4-Notebook-PC:~$ python twist.py
Calling FFC just-in-time (JIT) compiler, this may take some time.
Traceback (most recent call last):
  File "twist.py", line 38, in <module>
    u = twist.solve()

    self.solver = StaticMomentumBalanceSolver(self, self.parameters["solver_parameters"])
  File "/usr/local/lib/python2.7/dist-packages/cbc/twist/solution_algorithms.py", line 40, in __init__
    vector)

    return _cpp.error(*args)

Do the demos that comes with twist work?

Hi Kent, yes I just ran it. I must have missed something when I copied it. MANY thanks!!!

After doing:

bzr branch lp:cbc.solve

did you do:

sudo python setup.py install?

That is not necessary. Enter the demo directory and read the README
files.
