Mailman 3 February 2014 - SfePy

by Robert Cimrman

In examples/large_deformation/hyperelastic.py a rotation by displacements is applied. By using a similar function the vectors defining the force couples could be defined for dw_surface_ltr (IMHO). Does it make sense? r. ----- Reply message ----- From: "Andre Smit" <freev...(a)gmail.com> To: <sfepy...(a)googlegroups.com> Subject: Torque Date: Sat, Dec 18, 2010 05:10 What is the best way to apply a torque load to a model? -- Andre -- You received this message because you are subscribed to the Google Groups "sfepy-devel" group.

1D line elements in SfePy

by Nimish

I am currrently looking for FEM packages to help me solve a system of beams and columns, basically a collection of 1D bernoulli/timoshenko line elements. I started reading SfePy docs and i am getting the idea that doing the above is not really possible here, am i right? Are only 2D area elements permitted in SfePy? Or is there any direct support for solving 1D line elements too.. Cheers Nimish

Python 3 compatibility

by Robert Cimrman

FYI: As SciPy 0.12.0 is out and one of the release highlights is "Support for Python 2 and Python 3 from the same code base (no more 2to3)", we can think seriously about updating SfePy in this respect as well, cf. [1]. r. [1] https://github.com/sfepy/sfepy/issues/164

Evaluate a solution in the arbitrary point in the domain

by Alec Kalinin

Dear SfePy users, Is it possible to evaluate a solution not only in the FEM mesh node, but in any arbitrary point in the domain with the given (x, y, z) coordinates? For example, consider Dirichlet problem for Poisson equation. We apply essential boundary conditions on the surface nodes and after the problem has been solved we have the solution vector, i.e. vector of values in the FEM mesh nodes. But I want to know the solution in point v(x, y, z) that is not FEM mesh node. What is the best way to obtain solution in this point v? Sincerely, Alec Kalinin

ANN: SfePy 2014.1

by Robert Cimrman

I am pleased to announce release 2014.1 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 Mailing list: http://groups.google.com/group/sfepy-devel Git (source) repository, issue tracker, wiki: http://github.com/sfepy Highlights of this release -------------------------- - sfepy.fem was split to separate FEM-specific and general modules - lower memory usage by creating active DOF connectivities directly from field connectivities - new handling of field and variable shapes - clean up: many obsolete modules were removed, all module names follow naming conventions 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, Matyáš Novák, Jaroslav Vondřejc

clean up and sfepy.fem split

by Robert Cimrman

Hi, several important changes for users of "SfePy as a library to build apps" will be in the next release of SfePy (to be soon) and are already in the master repository. Those are: 1. sfepy.fem has been reorganized and split into code that is discretization method independent (now in sfepy.discrete and sfepy.discrete.common) and FEM specific (now in sfepy.discrete.fem). 2. all source files in the repository now use the same naming conventions (no more thisStyle.py modules, only this_style.py). 3. isfepy was removed, see the docs for an advice how to setup ipython for the same functionality. 4. a number of unused/underused modules were removed. If you have any feedback, do not hesitate to post. Regards, r.

remove isfepy

by Robert Cimrman

FYI: I am going to remove the isfepy ipython-based shell from sfepy, as it has not much value over plain ipython. An information will be added to the docs saying what to put into an ipython startup file to get the same functionality. r.
