Topic: I want to optimize finite element tearing and interconnecting

Hi folks

I am very interested in FETI,so I want to optimize this program,but i need your tips.

1.Has OOFEM  used the FETI method by default?

2.Is there any documentation about FETI being called?

Thank you very much my friends

Hi,
No, oofem is not using FETI by default. There is, however, an prototype example of FETI solver implementation inside OOFEM (src/sm/FETISolver) exists, but has not been touched for a while, needs improvements and testing.

Thank you very much for Borek support.

I did not find out how to call FETI in Input Data Format Specification. It is a key issue for me.

What command can I enter to call the FETI solver in OOFEM?

Thank you again for your support.

Hi, attached you can find simple example with FETI solver. It should explain how to set up the solver.
The simulation should be run like this: mpirun -np 2 oofem -p -f partest.in
