I guess so :) You are interested in modeling a single chain, not the whole
microstructure, right? (BTW. if you are interested in modeling the whole "box"
with many chains, check ).

These are general steps, not particular to sfepy:
First you need to create a FE mesh out of the CT data. There are probably many
packages that can do that. I am familiar (and know it works) with , which
has been created by Vladimir Lukes, another sfepy developer.
Then you need to define the problem - specify boundary conditions, choose FE
approximation, apply loads and finally solve and visualize.

Check the wiki page  and possibly the references given there.
If you have other questions, we can discuss off-list, or on the sfepy mailing
