How Gmsh can creat hexahedra by save as .mesh file
by Kid Guo 04 Jun '15

04 Jun '15

Hi I'm using SfePy to solve a problem.Firstly, I creat a simple cube by Gmsh and save as my.mesh file. Now I am using sfepy/examples/multi_physics/biot.py to calculate.but it something wrong. Then I open the "/meshes/3d/cube_medium_hexa.mesh",in the "cube_medium_hexa.mesh" file,it consists Vertices and Hexahedra.But in my mesh file,it only consists Vertices,Edges and Triangles,no Hexahedra. When I run the biot.py, there aren't any results I want. How can I save .mesh file including Hexahedra? I think it is the main probelm. Regards, Kid

Elasticity with periodic boundary condition
by Ronghai Wu 03 Jun '15

Dear Robert Cimrman, I am trying to implement elastic inclusion problem. It is a 2D mesh with an inclusion(and therefore eigenstrain) at mesh centre. I developed my codes(as attached) based on following two previous issues. https://groups.google.com/forum/#!searchin/sfepy-devel/Ronghai/sfepy-devel/… https://groups.google.com/forum/#!searchin/sfepy-devel/elastic$20periodic$2… But I have troubles with the boundary conditions. I would like to try two kinds of boundary conditions: (1) Top and bottom boundaries: uniaxial loading(or surface traction). Left and Right boundaries: periodic. I used "dw_tl_surface_traction" but some errors come out. (2) Periodic at all boundaries. I think there must be a easy way for this, but failed to find out in SfePy documentation and mailing list. Could you please give me some help. Thanks. Regards Ronghai
