ANN: SfePy 2013.3
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 under the new BSD license. Home page: http://sfepy.org Downloads, mailing list, wiki: http://code.google.com/p/sfepy/ 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). [1] http://sfepy.org/doc-devel/users_guide.html#regions For full release notes see http://docs.sfepy.org/doc/release_notes.html#id1 (rather long and technical). Best regards, Robert Cimrman and Contributors (*) (*) Contributors to this release (alphabetical order): Vladimír Lukeš
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?

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 [1]).
How can I do that?
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 [2], 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.
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?
Check the wiki page [3] and possibly the references given there. If you have other questions, we can discuss off-list, or on the sfepy mailing list [4]. Best regards, r.
