FRF analysis ERROR # 151

Recommended Posts

Guest

Hi Prakash,

 

I am running a Direct FRF analysis in Optistruct. I have asked out on only 2 frequencies. I am attaching my .out and .stat file here and error message also. Please resolve my issue.

 

 

*** ERROR # 151 ***

 

Error accessing the scratch files:

 

error encountered in subroutine "xzslvn"

 

Solver error no. = -410

 

index = 1

 

This may be caused by insufficient disk space or some other

 

system resource related limitations.

 

(e.g. The Operating System or NFS cannot handle file size > 2 GB.)

 

This error was detected in subroutine inptvmc.

 

**** ABORTING RUN DUE TO UNEXPECTED ERROR CONDITION ****

 

**** Job completed ****

 

Thanks

Hemanshu

Hi @hemanshu

 

Do you have read and write permissions on the machine which you are working on?

 

Try to assign a temporary directory to write and access scratch files using TEMPDIR. Go to ControlCards>>TEMPDIR and give the path.

Hi Prakash,

 

My solution requires estimated disk space of 1.1 TB for scratch files, and i have it in two drives as F drive - 900 GB, and E drive -300 GB.

 

I am able to assign one drive as tmpdir for scratch files as TMPDIR= FILESIZE=300, E:\TMP   

When i am solving my file in F drive.

It is still showing that less space for scratch files. So i have aborted the run. I am attaching .out and .stat file also.

 

Is it possible to solve this model by this method  or i need to assign two temp directories or something else.

 

Thanks,

Hemanshu

Hi Hemanshu,

 

Can you check for which frequency it is taking more space?

 

Check if -fixlen command solves your problem. Follow few of these suggestions:

1) close all unnecceasy programs and application which utilize the machine memory

2) If possible cleaup diskspace

 

Meanwhile I will check if there a way to combine two directory for temporary usage.

Hi Prakash,

 

Thanks For the above suggestions. I have tried simulating my problem with above options, but was not able to solve it. Now i am trying to buy a new computer hard drive.

 

Thanks

Hemanshu
