In message file of ABAQUS I obtain " rotation correction and displacement correction is too large compared to rotation or displacement increments respectively. How I can solve this one.
Hi Debela Negasa Gurmu,
Try to customize Cαn .Acording to manual: “Cαn is the convergence criterion for the ratio of the largest solution correction to the largest corresponding incremental solution value. The default value is Cαn = 10−2. In addition to sufficiently small residuals, Abaqus/Standard requires that the largest correction to the solution value be small in comparison to the largest corresponding incremental solution value. Some analyses may not require such accuracy, thus permitting this ratio to be increased. To avoid testing the magnitude of the solution correction, you can set Cαn to 1.0.”
To modify the solution correction control, go to Step module: Other->General Solution Controls->Edit.
