I have given non linear properties of RCC beam in Abaqus but while analysis it showing error like "Time increment is less than the minimum specified" . so, How to fix this error ? help would be appreciated.
Hi
this error means your model diverge. there are many reasons make your model diverges.
so please describe your model in more details.
You can either reduce the minimum specified or fix your boundary conditions, element specifications, etc. As Raafat suggested, this could have many reasons.
send me an e-mail to [email protected]
then i will send you a report concening with rc simply supported beam (comparison with experiments)
best regards
It means you are applying load or displacement much more then the capacity of the structure. Reduce it and go to results. You will see the structure distortion. Even if the job is distorted.
Dear Tufai Mabood,
Thank you for your information. I have resolved the same error by changing the load amplitude (such as from 1MPa to 10 kPa in my case).
Change your step and use Dynamic, Explicit type rather than Static, General. Because in most cases, you have a problem with convergence. In Dynamic, Explicit, the solution is not exact and it's approximate and it'll solve your problem.
Dear Suman,
Perhaps you have done with static. Decreases time increment, change the load amplitude you will solve the problem.
Hope it is helpful to you.

Dear all I am solving pile pile cap interaction subjected to combined loading in Abaqus General standard ,but I faced two interchangeable problems the first one is '' too many attempts are made for the increment'' message is generated and when I increase the solver of IA to 30 ''time increment required is less than the minimum'' is also caused finally I tried to use ABAQUS dynamic explicit quasi-static step but the displacement vs time graph is can not be smooth what ever the time increased or decreased all possible steps I used but I can solve please if any one rise me up
