Unable to Write to Model Scratch File FEMAP8.1
Unable to Write to Model Scratch File FEMAP8.1
(OP)
Hello,
I am having trouble with loading resutls into FEMAP8.1/MSC Nastran2001. I am trying to import a .op2 file about 1.7Gb in size. Every time I try I get an error when the scratch file reaches about 2.1Gb in size. Co-workers have been able to import .op2 files in excess of 3Gb...what am I doing wrong?

I have moved the scratch file to other disks, but it continues to bomb out when the scratch file gets to 2.1Gb.
Any ideas would be much appreciated,
Best regards,
JohnyGluebag.

I am using windows xp, 1Gb ram, 4Gb page file, NTFS. I am consulting out of a clients office and using there computers...just got admin rights the other day so to change some stuff.
When I get it sorted I will post what the fix is.

Personally I have imported much larger file into FEMAP but I'm not absolutely sure about ver 8.1. Ver 8.3 I know can handle 10 GB or larger. But 2.1 GB like Greg said clearly indicates a FAT-problem.
Good Luck

I then did some comparisons between importing the same results using femap 8.1 and femap 9.0. Femap 9.0 is much faster at importing results. Load time went from 1.5 hours with femap 8.1 to approx 40mins with femap 9.0
When I get time I am going to reinstall femap 8.1. I figure I must have changed some parameter or something. I wish I could explain exactly why the problem occured and how to fix it, but for now I am happy (and lucky) that femap 9 is getting the job done.

Now I have a whole new set of stuff to figure out. How to couple acoustic elements and plate elements in Nastran, and run a nonlinear-transient analysis...
Its going to be a long week.
