Time increment required is less than the minimum specified

[Hussain2339]

Dear All,

I am simulating a 4-Point bending test and I got the following error

.

Error in job Small: Time increment required is less than the minimum specified
Error in job Small: THE ANALYSIS HAS BEEN TERMINATED DUE TO PREVIOUS ERRORS. ALL OUTPUT REQUESTS HAVE BEEN WRITTEN FOR THE LAST CONVERGED INCREMENT.
Job Small: Abaqus/Standard aborted due to errors.
Error in job Small: Abaqus/Standard Analysis exited with an error - Please see the message file for possible error messages if the file exists.
Job Small aborted due to errors.

This error is very general and indicates convergence problems. Theoretically, you could try decreasing the minimum time increment but it rarely helps. Instead, you should find the reason for non-convergence and fix it. Try refining the mesh, make sure that material properties (especially plasticity) are correct and verify the behavior of contact in this model.
