Elmer Discussion Forum

Hello,

I am trying to simulate multi-body contact in Elmer. Is there any examples or references that are available as a case study?

Hi

Contact mechanics is something that is currently under development. The target is to be able deal with cases where contact surface pairs are a priori known. Multibody contact are not yet planned, as far as I know.

Hi Peter,

If I understand, it is still not possible to perform this kind of analysis? :

When do you plan to release this feature ?

Thanks
Pierre

Hi Pierre,

Well, the animation was done with the public version. All contact mechanics code is immediately available at

https://github.com/ElmerCSC/elmerfem

There is a "contact" branch. Unfortunately documentation and test cases or lagging behind.

@Peter, I just can't find this contact branch you are talking about. I saw the video on youtube and it is a great place for me to start. I would appreciate if you could share the .sif and other files including geometry and mesh etc. thanks in advance.

Hi

The "contact" branch has been long since merged with the "devel" branch.

Hi

There are some test cases for the contact named "Contact*". The animation on the youtube is closest to ContactBlunt2Dslide test case.

@Peter thanks a lot for your help. I think I found the test you referred to here:
