Hi,

I am running a cyclic model of perforated beam-to-column connection. When I on the NLGEOM option in STEP, I received an Error as stated below:

Time increment required is less than the minimum specified.

The analysis has been terminated due to previous errors.

All output requests have been written for the last converged increment.Abaqus/Standard Analysis exited with an error - Please see the  message file for possible error messages if the file exists.

I have also added plastic strain and yield stresses to my model. 

Please help.

Thanks
