How to READ and UNDERSTAND ABAQUS Files

[@jude532]

I'm a PhD student struggling with Abaqus and I am grateful for the quality of your videos and explanations. Thank you - you help more people than you realize.

You are so welcome @Jude! That is why I started the channel, to help as many people as possible and I really appreciate this encouraging comment. Thank you very much!

Glad it helped! Thank you for your interest in the channel.

No *.res file which is use when you restart calculation

[@MichaelOkereke]

You are absolutely right.

Dear Michael, How about .stt file? It does consume a lot of memory..

[@MichaelOkereke]

Hello, This is a good point. The .stt file is a state file used in ABAQUS to store information about the simulation at every timestep during the simulation. It is basically the workhorse of ABAQUS and captures not only the time-step simulation information associated with the simulation. For example, whilst the ODB file may store the results after a successful convergence within a time step, the .stt file will store every the iterations that led to a successful result. This is why, often for highly nonlinear simulations, the .stt file will be bigger than the ODB file. What you can do to reduce the memory load is to ask ABAQUS to only write to the .stt file at certain frequencies (where you demand for that output of interest). I did not include it in my list but certainly it can be. Infact, here is an extensive list of all possible file extension types in ABAQUS: classes.engineering.wustl.edu/2009/spring/mase5513/abaqus/docs/v6.6/books/usb/default.htm?startat=pt01ch03s05aus29.html

@@MichaelOkereke Dear Professor, then can I delete those stt files once I finish with my simulation, provided I don't need any restart analysis further?

[@MichaelOkereke]

Yes in deed

[@CuongNguyen-tt4jp]

I created a model and run it and get the results. then I copied the .cae file only to create new model. but this .cae file is too heavy compared with the case that I create a new model. what are the reason and how can we modify the copied .cae file to be small? thanks!

[@MichaelOkereke]

I am not sure @Curong Nguyem what is going on. Is it possible that in copying across your new model that you also included all the ODB files and results file that come with the completed simulation. If you want to recreate a model, maybe you should find the journal file (with extension *.jnl*) which you can use to recreate the model by running it as a Python script. It is simple a python script, a textbased script, so not too big. YOu will not have the problem with file size if you decide to a jounal file. You can learn about ABAQUS file times from this video of mine about this: kzbin.info/www/bejne/l6aalISHipelo6c
