Hi all

Did you guys get to a conclusion on this topic? I am very interested in that 
and will be glad to hear your advices. Can I help in any sense?

Rgds,
Renato

Hi Andrea,

Thanks for the answer!

Let me try to broaden a little this thread:

I can imagine this has been done before in application code. So ...
Does anyone have examples or pointers to suggestions of
straightforward implementations of cohesive zones in libmesh?
Do you guys know someone I could e-mail directly - perhaps published
papers or so?

Thanks once again!
Renato

Re: [Libmesh-users] Cohesive elements support?

Dear Renato,

I'm not working directly with libmesh, but rather I'm using the MOOSE framework 
(http://mooseframework.org), which is based on libemesh. My understanding is 
that libmesh does not support cohesive elements and, as today, there is no plan 
to implement this feature because the same results can be achieved by using 
interface and constraints.

I'm working on implementing a cohesive zone model in MOOSE but I don't know if 
what I'm doing can be translated to libmesh directly, as I'm not really 
familiar with it.


John please correct me if I said something wrong.


Hope this help.

Andrea,

libMesh does not currently support cohesive elements. I suggest you keep
working with Ben Spencer and Wen Jiang on this topic to identify what
changes will be required in libmesh to support them.

[Libmesh-users] Cohesive elements support?

2018-02-12 Thread Rovinelli, Andrea 
Hi there,
I’m new to libmesh so this may be a silly question but from the doxygen I 
wasn’t able to get an answer.
Does libmesh support cohesive elements?
If not why (There is another way to implement a cohesive zone in libmesh)?
Also can somebody give me some hint on how to implement them? What do I need to 
subclass and the major modification needed?
Thanks
