Re: Torque

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 22 Jan '16

22 Jan '16

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

Robin boundary conditions
by patricia...＠upf.edu 07 Dec '14

Hi all, I wanted to apply Robin boundary conditions, in the nearly-incompressible hyperelastic model (Mooney Rivlin), using the 3D cylinder mesh. The Robin boundary condition should be like: S·n + a·u = 0, where S is the stress, n is the the normal vector to the surface, u is the displacement, and a is a parameter representing the elastic response due to the presence of surrounding tissue (for example 1·10^-2),. Robin BC are imposed on Gamma_R = Gamma, the surface of the cylinder. How can I implement this? Thanks a lot!
