Re: [Getfem-users] large sliding/deformation contact friction bricks working?

[Konstantinos Poulios]

Hi Bernd,

for large sliding contact you can use the integral contact brick with raytracing which is fully implemented and should actually be superior to nodal formulations and formulations with projection. You can find an example of how to use the brick in:

http://svn.gna.org/viewcvs/getfem/trunk/getfem/interface/tests/matlab/demo_large_sliding_contact.m

or if you prefer python in:

http://svn.gna.org/viewcvs/getfem/trunk/getfem/interface/tests/python/demo_large_sliding_contact.py

If you need contact with only small sliding, there are many bricks based on either nodal or integral formulations to choose from. The integral ones also support MPI for parallel runs. I have used them for solving many different problems with contact.

Best regards

Kostas

Hello dear getfem-sers,

I am new to getfem++. Reading the user-documentation about large sliding/large deformation contact with friction bricks - i came across the statement that the nodal-brick with projection does not work.
Does that mean, that all the information on
  http://download.gna.org/getfem/html/homepage/userdoc/model_contact_friction_large_sliding.html?highlight=friction
are future thinking, or that most parts are working (which ones?)?

Does someone here have experience with using getfem++ for contact mechanics?

Thanks
Bernd
