Abaqus Crash

[mizzjoey]

Hi.

I would like to ask for help from anyone who has experience troubleshooting abaqus. I was working in CAE (module: part) and editing my sketches when suddenly abaqus shut down due to some error. I tried re-opening my cae file but I received this error msg instead:

#: Executing "onCaeStartup()" in the site directory ...
openMdb('oring.cae')
#* rfm_TableRepr::rfm_TableRepr: ABAQUS Database table format is corrupt. This
#* may indicate a corrupt database, or it may indicate that the analysis code
#* preprocessor is still writing the database.
#* If you suspect the latter possibility, please attempt to reopen the
#* database when the preprocessor is complete.

I wonder what is wrong with it. Is the cae file corrupt now? Do I have to re-do the model all over again (I'm on a tight schedule)? What can I do to avoid this from recurring?

Any explanations and suggestions are very much appreciated.

thanks,
jo

Mizzjoey,
I am not sure why this happened to your cae file. You may be able to recreate the cae file using the replay file "abaqus.rpy.#" where # is probably the highest number in your directory. This file is a recording of every key stroke and button click. I hope this helps.

Thanks, rstupplebeen.

abaqus.rpy file wasn't helpful in this case because I tried opening the files so many time my attempts have wiped out the records of my original work. I'll remember to use the rpy file next time. Thanks for the info.

A senior engineer told me that Abaqus deos crash from time to time for some unknown reason. I wish the guys in Abaqus would take a look into this soon.

Have you sent the file to Abaqus support? They don't use a posting on a forum like this to diagnose a customer's issue. They have official channels for this...

By the way, the best way to recover the corrupted file is through the jnl (journal) file. It will have the same name as the .cae database, just with the .jnl extension.

There is help on this in the docs:
V6.6 Abaqus/CAE Users' Manual, section 9.5.2 (Recreating a saved model database)

Thanks brep. I've sent the file to my senior, he says he has yet to file the problem to Abaqus constructively, seeing as this is a random occurence.

I guess it's just frustrating to have the random occurence occur to you when you least expect it. Heh.

Thanks for the pointers on jnl file and users' manual!

regards,
jo

I have started to back up my CAE file in stage after I losted 2 weeks of modelling work from past experence. However, those error usually occur when the ABAQUS crashed when it is doing the saving.
I think what ABAQUS should do is to make a copy of the old file before overwriting the old one, at least we won't lost all the work.
