<p>I am working on crack identification in RC bridge girder.&nbsp;</p>
<p>Can anyone tell me about " what is ment by insurmountable convergence failure"</p>
<p>&nbsp;</p>

I am structural engineering student , working on discrete and smeared model of 1/4 th scale bridge girder using ANSYS software and facing some problems.Some problems regarding discrete approach are: 1. can I use beam188 instead of link180 for modeling reinforcing steel???2. what should I use value of shear transfer coefficient for open and closed crack ?? what is criteria for using these coefficient??3. How can I apply load in multi-steps (load step1 ,load step2 ,load step3. etc) ???4. How can I set convergence criteria???
