Re: Torque
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?

What is the best way to apply a torque load to a model?

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

Robin boundary conditions
by patricia...＠upf.edu
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!
