Yes! Provided the terms used in the weak form of a PDE are already implemented in sfepy. If not, one needs to add them, which may be non-trivial.

what extra step should i take in doing time-step analysis? i need to do an analysis which involves 300 time-steps, with 100 constants in each time-step. the problem is a multi-scale mass-heat transfer related.

Check out the time-dependent examples, e.g.
examples/diffusion/time_poisson.py (long syntax) examples/diffusion/laplace_time_ebcs.py (short syntax, changing boundary condition nodes)
Basically, just define the time-stepping solver, and if it's a dynamic simulation, add some terms with time derivatives of variables, like dT/dt in the first example above.
What do you mean by "100 constants"?
r.
well, technically they are not constants, they are variables with given values. but the values change in each time step, much like coefficient changing with time.
is the time-stepping solver different than the standard solver in sfepy? i thought sfepy has built-in time-stepping function.

No, it is standard. The examples I mentioned show how to use it.
