Topic: Example problems with adaptive remeshing and contact

Hello,

I was wondering if there are any example problems using adaptive remeshing and contact? I searched the "tests" directory of the source file zip folder, but cannot find any....does anyone know of any?

Re: Example problems with adaptive remeshing and contact

Dear Abhishek,
I can provide some examples illustrating the adaptive solution of crack propagation problems. In fact, only fracture material models support the adaptivity right now, the other material model need to be extended to allow this. Such an extension requires to decide which variables to map, selecting suitable mapping algorithms, etc. Same of these steps are well supported by available functionality in oofem.

Concerning the contacts: there are only interface elements, that allow to model contact in some cases, but their capability is limited (predefined contact area). There has been some recent work of one of our students on contacts with rigid body to simulate nanoindentation tests. 

Let me know, if you are interested in these examples.

Borek.

Re: Example problems with adaptive remeshing and contact

Dear Borek,

Thanks for the reply. The problem I want to simulate is lateral crushing of a tube between two dies. I think I will require plasticity, adaptive remeshing and contact. Of course, the dies can be modeled as rigid bodies. I think, the input files used for simulating the nano-indentation tests might be of use to me......would definitely like to have a look through them.
