passing parameters, and time dependent forces

[alxgom]

Hi, I really like your implementation.

I'm trying to use it to run some nonlinear simulations, and i've managed to adimensionalize the code to use it for 'non-physical' processes.
However i'm not sure how to input a time-dependent force, since non of the examples include this case.
I'm also struggling to pass keyword arguments for the force parameters, if you have any tip on how o do that, i'd really appreciate it.

I'm also modifying the code to use non-symmetrical domains. But hopefully i'll have that done fairly quick.

Cheers,
Alexis
