I'm new DIANA user and now I am working in numerical analysis of reinforcement concrete infilled frames with DIANA.
So I have a problem when it comes to running the model. After results these errors appears
SEVERITY : FATAL
ERROR CODE: /DIANA/AP/LB40/0053
ERRORMSG.F: Divergence occurred, iteration method failed.
Use smaller load steps, different iteration procedure or different
control procedure. Restart from a saved FILOS file or rerun the
complete job.
SEVERITY : ABORT
ERROR CODE: /DIANA/LB/ER50/0098
ERRORMSG.A: 1 fatal error messages occurred during previous analysis.
Can't continue.
DIANA-JOB ABORTED
I let you check my model whether you can bring your experience in.
Thanks in advance
Dear Prost Balenda ,
The problem is in modeling the behavior of the infilled material and its links to the frame. It is also important to use correct hysteresis model to describe the non-linear behavior of the infilled material.

Dear Prost Balenda ,
In addition to the answer above, I wouold say that the method in numerical modeling is to begin first with everything with elasrtic behavior and to compare the results with an analytical study. It will help you as well to be sure the problem is in the model itself and not in the definition of the behavior of the elements.
For the hysteresis behavior, search the Equivalent Strut Model. Several hysteresis behavior exist.
