Maximum Time Step Problems in ABAQUS
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?

Have you tryed to set the
Have you tryed to set the minimum and maximum timestep to the same value (in CAE)?
Mabe the line should look like :
*Static, allsdtol=0, continue=NO
0.05, 1., 0.05, 0.05
You also could have a look in the documentary

Are you changing any default control parameters?

Hi Akumar, thanks
Hi Akumar,
thanks for the reply, yes I have found that I am modifying the time step using the VCCT linear scaling option. I wasn't aware that this would override the maximum time step, but I supose it makes sense.

glad to know it resolved your problem :)
