CORRECTING THE TIME INTERVALS IN ABAQUS
CORRECTING THE TIME INTERVALS IN ABAQUS
(OP)
Hi. I am very new to Abaqus but have to use it for my dissertation. I have just finished modelling a 2D multi-layered beam with crack surface at the bottom right end. Haven meshed it and all i couldn't get the model to run as it kept on coming up with this error:
"OUTPUT WAS SPECIFIED IN NUMBER INTERVALS AND THE CORRESPONDING TIME INTERVAL AT WHICH OUTPUT IS TO BE WRITTEN, 3.33333E-05, IS SMALLER THAN THE MINIMUM TIME INCREMENT ALLOWED IN THIS STEP, 1.00000E-03."
I am at a loss about what to do to correct this.... Can any1 help me here.
Thanks.

RE: CORRECTING THE TIME INTERVALS IN ABAQUS
I have some suggestions,
1)set the minimum time increment as it is suggested by abaqus
edit step> incrementation tab
2)Pay attention to the type of step u mentioned, static/ dynamic explicit ...., are you sure it is suitable for your simulation?
3) refine your mesh (make it smaller)
I hope it will help u

I have corrected the initial time to 5, Minimum to 5E-0005 and maximum to 5 and the model ran.
It seems not to still be correct as both the results for the deformed and undeformed shape look alike.
Could you please help look at the model in the attached file in my first post and help figure what the problem is?
Thank You..

By the way, you should upload the INP or the CAE. I prefer INPs because sometimes CAEs can be from an older version of ABAQUS and if JNLs aren't uploaded along with its CAE, they are useless. However, CAEs can be much smaller in size.

Please attach .CAE or .inp
By looking your previous model, I recommend u to change some parts
1. I think you should have large deformation in this model, so please change static, general type of step to Dynamic Explicit
2. Pay attention to the step you specified for the boundary condition and loading.
3. I don't understand your analysis, how could you apply load with that above curve?
4. In interaction, you have chosen frictionless, it means there is no resistance.
