How to make the convergency of analysis better
How to make the convergency of analysis better
I want to simulate a test of a RC frame under cyclic static displacement.That is a very usual test. The maximum displacement is 170mm, but when the displacement reach to the 30mm, the analysis terminated. How to make the analysis convergency better.I use the MP model for rebar and Mander model for concrete.

Dear jamesli,
This (convergence) topic is discussed already in tens of past posts in this Forum. It is also extensively touched upon in the Help System (especially in the many 'Notes' found in the latter).
Hence, we strongly recommend you to carry out a search in this Forum (using strings such as "convergence" and/or "divergence") and to read the Help System with care.
You will easily realise that there could be multiple reasons for the lack of convergence you are observing, including modelling errors.
