    Accidentally combined output files without requesting history outputs, can I reverse this?

    I just finished running a large job which took many hours to complete, and I had to do a restart job as well since it froze near the end. When I combined the two odb files (original and restart), I forgot to request to keep the history outputs which are crucial for my results. Is there any way...

    How to properly define the CDP material in Abaqus?

    Thank you, I am trying that now. How do I use this to tell if my material is correct? And if it is not, how do I fix it?

    How to properly define the CDP material in Abaqus?

    I am simulating biaxial cyclic loadings on a post-tensioned segmental concrete column in Abaqus. I apply the loads as boundary conditions to the loading block with displacement vs time amplitudes. When the job runs and I have a look at the results and plot displacement vs. reaction force, the...

    How can I apply biaxial cyclic loading to a column in ABAQUS?

    I am a final year student trying to study the behaviour of segmental columns subjected to biaxial cyclic loadings using Abaqus but am having some issues. When I apply uniaxial cyclic loading it is fine and runs properly with correct results. However, when I try to apply biaxial cyclic loadings...

    ABAQUS - Student new to software, keep getting error messages when running job - please help!

    What could cause this? Those warnings for the displacement increment being too big are during Step-1 which is where I create H-and F-Outputs 1. The interactions are created in the Initial step, as well as the BCs and the predefined field for the tendon initial stress. The loads are not actually...

    ABAQUS - Student new to software, keep getting error messages when running job - please help!

    Hi everyone, I am currently completing my final year research project on the seismic performance of segmental columns and I am using Abaqus to run the simulations. I am brand new to Abaqus, and since my supervisor has never used the software before I am having to teach everything to myself...

    ABAQUS job has submitted, but does not run even after weeks. Anyone able to help fix this issue?

    It appears to be running and working properly now, thanks for your help!

    ABAQUS job has submitted, but does not run even after weeks. Anyone able to help fix this issue?

    How do I know how to fix this issue and make my model properly constrained? Most of the nodes of zero pivot or numerical singularities are in the portion of the steel ED bars which are unbonded to the surrounding concrete. I was unsure of how to have it unbonded so I didn't apply any...

    ABAQUS job has submitted, but does not run even after weeks. Anyone able to help fix this issue?

    It wasn't working using the command window just before, but it works for me now, thank you! However I have a new issue - when my job begins to run it then says "an unhandled exception occurred" and quickly aborts and says it "encountered EXCEPTION_ACCESS_VIOLATION in ntdll.dll (code...

    ABAQUS job has submitted, but does not run even after weeks. Anyone able to help fix this issue?

    I have a very strong feeling that it is a licensing issue, but I am not sure. Is it possible that one of the earlier jobs I submitted and deleted could have had an error and cannot run so it is now clogging up the queue for the server? I have checked Task Manager and there isn't anything...

    ABAQUS job has submitted, but does not run even after weeks. Anyone able to help fix this issue?

    Hey everyone, I am using ABAQUS to run some cyclic loading tests on a series of segmental columns for my final year thesis. I have tried to submit my first job for analysis but it never runs, it just says "submitted". The .log files still say the job is in the queue, but I have been having the...
