While running a dynamic explicit analysis in abaqus, job is getting aborted after a total time of 0.17seconds (after 2 to 3 hours of running).
The model includes a soil slope, a pile with 0.25m dia and 4m long with longitudinal and lateral reinforcements. Can you please suggest a solution?
Hi,
It is hard to say without seeing the error file. Can you add a copy?
C
Hi..
I think the program runs using single precision.
Sir,
The program is now running without aborting.
But it takes about 12-24 hours to complete. Could you please suggest a method to reduce the running time?
Thank you
In Abaqus/Explicit computation time mainly depends upon (1) stable time increment and (2) overall time. To increase (1): use Courant estimate delta_t = delta_x / cP, where delta_t stable time increment, delta_x - mesh size, and cP is bulk wave speed, the latter can be roughly estimated by cP = sqrt(E/ro) with E Young's modulus and ro density. So, either increse E, or (preferable) decrease ro, or use more coarse mesh. Usually, computation time may be considerably decreased by specifying larger processor number at Job module.
Aswathy Padmanabhan i have problem like your one
While running a static analysis under cyclic load in abaqus, job is getting aborted.
could you help me?
To get more stable results at modelling cyclic loadings, in case of accumulated large deformations (that is the most common reason for the Abaqus failure), try to use either 1) Hourglass control (if your elements are with reduced integration), or 2) move to element with full integration, or 3) work with element deletion, that should be coupled with a damage evolution criterion (in material specification).
Thanks very much sir for your response
Kindly if you can help me how can i determine this criteria in abaqus....
I'm new with abaqus software and having similar problem, the job have been created successfully. after checking the result and while viewing the animation i got this error.....
Error in job DPR_Job: Time increment required is less than the minimum specified
Error in job DPR_Job: THE ANALYSIS HAS BEEN TERMINATED DUE TO PREVIOUS ERRORS. ALL OUTPUT REQUESTS HAVE BEEN WRITTEN FOR THE LAST CONVERGED INCREMENT.

I am getting the above two statement in abaqus after running the job.
I kindly ask for assistance in case anyone has faced this before
Hi Espoir,
If you post your CAE or INP file, I can spend some time to see what iswri=ong with it.
Sirous Yasseri Please find the CAE file uploaded bellow.
Thank you Sirous Yasseri
Sirous Yasseri COULD YOU SUPPORT ME WITH MY FILE CAE. DO I HAVE THE SAME PROBLEM AM I USING ELEMENTS SHELL COULD YOU SUPPORT ME?
