*** INTERNAL PROGRAMMING ERROR # 8008 ***

Recommended Posts

Hello,

 

 

I am getting the following error after running a calculation. I have done some research and according to that, it's because I dont have enough disk space, but I have 64 GB available in my disk. Can someone please help me out? The calculation took me about 9 hours and I have to restart it. It says that the non linear analysis was ocnverged but it didnt create a .h3d file to view with hyperview. 

 

 

 *** INTERNAL PROGRAMMING ERROR # 8008 ***
 CHECK detects overwriting of data block: plsgau.
 * DATAMANAGER ERROR in subroutine "datamx".
 Array "cs2sres" was the first in memory after this array.

 

Thank you

 

Kind regards,

KBE

Hi @KBE

 

Can you share the .out file, please?

 

Hi Prakash, 

 

 Unfortunately I can't, as it's confidential. Could you please suggest some things I  could verify in my set up? I am also getting the following error with it.

 

*** INTERNAL PROGRAMMING ERROR # 8011 ***
 DELETE detects overwriting of data block: plsgau.
 * DATAMANAGER ERROR in subroutine "datamd".
 Re-checking all lenvec buffers

Hi

Under load you have placed Disc deplacement load colletor? Does it contain force data of SPC data?

Hi @Nachiket Kadu

 

The disc displacement is made of SPCDs.

Hi

You are trying to give displacement? If yes try giving it in SPC itself and then check.

 

I have done a model similar to this. The only difference is the size of the two cylinders that I am trying to encase.  I have already defined the necessary SPCs and the SPCDs for those SPCs. It worked with the first model but not working with this. I double checked all the constraints as well.

Hi @KBE

 

Can you share the list of output requested you have in your solver file?

 

Also, remove NLOUT and check if that helps.

Hi @Prakash Pagadala,

 

Is this what you meant? or did you want the output data requested in the global_output_request card?

Yes, 

 

Some result outputs are not compatible with NLOUTs and may end up using high scratch files. 

 

It would be better if you share at least the memory required and available memory information from .out file.

Did you want the information below?

  @KBE

 

clearly, the issue is with the memory and you can see this from the estimated and available memory information,

 

Can you remove GAUSS stress and try again?

 Yeah i could, but it takes hours for the calculation. Should i just run it and send you the memory information?

Tried this but there still isnt enough memory space. Is there another option?

Hi,

 

Can you share the output file (memory information from the latest)

 

You can use a temporary directory to let solver write scratch files. 

 

Please see the link: 

 

And, sorry for a late reply.

Hi Prakash,

 

I tried the first two steps that you mentioned yesterday. Closing all applications running and cleaning the disk, but I still had the same issue.

 

Where can I find the fixlen option? Is it in optistruct options or do I have to define it in a card?

 

Currently, my collegue is using the licence so I have to wait till he is done. I will try what you said and let you know. 

 

Thank you

KBE

Prakash,

 

I tried launching the calculation with fixlen but each time I enter a value for the memory, it requires more and the calculation fails. I first tried with 500, it required 540, so i entered 600 then it required 820 so then i entered 1000 and this  is what i got. 

 

 

*** ERROR # 7001 ***
 Not enough memory for preprocessing
 (total number of nonzero terms has not been determined)
 OptiStruct was executed with fixed memory size, which was not enough
 for the given run.  Please allocate more memory or use automatic memory
 allocation feature in OptiStruct.

 This error occurs in module "prpdrv".

The problem is, I did a similar calculation with the exact same configurations and it worked fine. 

 

Regards,

 

KBE

@KBE

 

Fixlen will not help.

 

You need to use TEMPDIR to write out scratch files. 

 

Please try that and if you still face the same error, then I request you to share the .out file to report the issue with developers.
