```Dear Robert.

Im intresting in modeling mechanical deformation of magnetorheological elastomers (material formed by inorganic chains inserting in a polymeric matrix -see figure 2 in the attached file-). The inorganic chais are like pearl necklace (are formed by saligned pheres ).

Can I use this tool (SfePy) for modeling the mechanical deformation (i.e.: shape deformation by appling a force in longitudinal and transversal direction respect to the inorganic chains)?

How can I do that?

Im a newby user of python and I dont know anything about simple finite elements analysis. What documentation (books or other) do yo recommend for my introduction in this topic?

Best Regards,
José Luis Mietta

I am pleased to announce release 2013.3 of SfePy.

Description
-----------
SfePy (simple finite elements in Python) is a software for solving
systems of coupled partial differential equations by the finite element
method. The code is based on NumPy and SciPy packages. It is distributed

Git (source) repository, issue tracker: http://github.com/sfepy

Highlights of this release
--------------------------
- implementation of Mesh topology data structures in C
- implementation of regions based on C Mesh (*)
- MultiProblem solver for conjugate solution of subproblems
- new advanced examples (vibro-acoustics, Stokes flow with slip conditions)

(*) Warning: region selection syntax has been changed in a principal way,
see [1]. Besides the simple renaming, all regions meant for boundary conditions
or boundary/surface integrals need to have their kind set explicitly to 'facet'
(or 'edge' in 2D, 'face' in 3D).

For full release notes see http://docs.sfepy.org/doc/release_notes.html#id1
(rather long and technical).

Best regards,
Robert Cimrman and Contributors (*)
