Re: file writing error when using a big mesh

Hi there, the error message only says the files can't be written. It may be discspace, but more likely its a matter of file size. Either your system-filesizelimit is to small (2-8 GB depends on platform) or you have a user-limitation (in unix: ulimit). Have a look at the filesize-estimation in the dat-file. I guess, the fct-file is the problem. In that case you can split it into several smaller files by adding the following to your enviroment-file (abaqus_v6.env): split_fct=["2000MB","2000MB","2000MB", ...] :-) Fuzzy "Ilia Hariton" <hariton@xxxxxxxxxxxxxxxxx> wrote: >Hi Albert, > >I think that's mean you have no disk space where the scratch files are written >(probably c:\ on a windows computer).

Re: a modeling problem in abaqus

Hello Jingfeng, It is good to hear that I could help you, at least in some way. I had never seen the message you got (I am not an expert), but I think it could be related to the interaction between the surfaces. Let´s see if I can explain it a little bit better. Once you have created both parts (the block and the sphere), you go to the assembly module to make your whole model. In that module, you can choose some kind of constraints (just for the beginning of the iterations), or you can go to the interaction module to define how the surface of your block and the surface of your sphere behave. You can define contacts, friction, constraints....it depends on what you want to simulate. If you have done all this and the message continue, I am afraid I can´t help you. Anyway, let me know if it worked. Good luck! David [Non-text portions of this message have been removed] ------------------------ Yahoo!

RE: file writing error when using a big mesh

Albert, If your number of degrees of freedom is very large and you have contact or other features in your model that create large temporary files, you may run out of disk space. So, when you run the job, watch the size of your temp. files and the amount of disk space left periodically. Another thing that I have run into with ABAQUS 6.3 running on Solaris is that there is bug which stops the job as soon as it starts writing into the .DAT file and gives the ERROR CODE 6 in the .LOG file, which means insufficient disk space. This happens rarely and I have not been able to determine what causes it. Good Luck Farshad -----Original Message----- From: Yong Sun [mailto:yongsun1979@xxxxxxxxx] Sent: Wednesday, December 10, 2003 1:52 PM To: ABAQUS@xxxxxxxxxxxxxxx Subject: [ABAQUS] file writing error when using a big mesh hello, all Is there anyone who got a 'file write' problem when using big mesh? I got a "unable to complete file write" error when I ran my 200,000 hexa elements electrical-thermo problem in abaqus standard 6. The error message wants me to check my disk space, but I am pretty sure I have enough, at least 10 Giga. Below is the error message: ***ERROR: UNABLE TO COMPLETE FILE WRITE. CHECK THAT SUFFICIENT DISK SPACE IS AVAILABLE. FILE IN USE AT FAILURE IS abaqus_job1_metsp.uft. Thanks, Albert Sun __________________________________ Do you Yahoo!? New Yahoo!
