migrating to @python.org

by Robert Cimrman

Hi everyone, as described in [1] I will do the move from Google groups to a new Mailman 3 mailing list on Python.org. I will try to do that on Monday 10.4. - all existing subscriptions will be transferred to the new list, and I will also port the content. Best regards, r.

Calculate diffusive flux from solution in interactive mode

by Scott Calabrese Barton

I've made a lot of progress learning sfepy this weekend but I'm stuck on post-processing. I'm in interactive mode (using Jupyter) using a toy model that solves the laplace equation on a rectangle with dirichlet conditions on the ends (image below). Now, I'd like to evaluate the flux at designated positions, say on a line or a set of points. I'm able to evaluate the flux field using: flux=pb.evaluate('ev_diffusion_velocity.3.Omega(s.D, c)', copy_materials=False, mode='qp') where 'c' is the solution field variable and s is the material. This produces a set of flux vectors at quadrature points. What I can't seem to do is put this data in a proper field variable so that I can evaluate it with probes, say for example at the boundaries. I've looked at the examples but have found them too complex to reduce to a few lines of code. Can anyone suggest the easiest way to get this data into a field variable? <https://lh3.googleusercontent.com/-IGio8BtAJJE/WOF2SY3wmCI/AAAAAAAAAKI/q9S1…>

From Solidworks to sfepy

by François Gingras

Hi all, I am new using Sfepy and I am trying to get a part from solidworks, mesh it (using whatever) and then do some FEA on Sfepy. So right now, I exported the part in STEP and used GMSH to generate the mesh. But the VTK/MESH mesh file contain more dans 1 cell type. So Sfepy pop this error : "meshes with several cell kinds are not supported!" I am trying to figure how to have only one cell kind. Is this seem right? Solidwork -> Step file -> Gmsh -> mesh/vtk file -> sfepy

Debian linux stretch OS Intel i5750 processor 64bit KDE desktop Directory structure: /root/anaconda3/lib/python3.5/site-packages/sfepy Home Directory structure: /home/gary/Downloads I am still trying to get a clean installation of sfepy. I am still missing vtk and pysparce libraries. I need to get components that are compatible with an amd-64, python3.x system. Any help with finding these packages and help with their installation will be sincerely appreciated. Thank you for your responses Gary R
