Hi,

I hape a relatively simple question. I am trying to set a maxmimum time step for a job by the lines:

*Static, allsdtol=0, continue=NO

0.05, 1., 1e-25, 0.05

so I believe the maximum time step should be 0.05 giving me a minimum of 20 increments in the step in total. However the STA file below shows that the job starts at 0.05 and the appears to ignore the maximum time step command. Can anyone tell me why this occurs?

Abaqus/Standard 6.10-2 DATE 08-Jan-2013 TIME 14:29:13

SUMMARY OF JOB INFORMATION:

STEP INC ATT SEVERE EQUIL TOTAL TOTAL STEP INC OF DOF IF

That sounds weird. Are you sure that the sta-file output comes from that specific step in that specific inp-file?

Hi Jorgen,

thanks for the reply.

They are both from the same files. Although I have since realised that I am including linear scaling with the VCCT method which appears to over-ride the maximum increment command.

Cheers
Jo
