Error # 8030
Altair EmployeeHallo,
I got the following error massage after starting a topology optimization.
*** Automatic resize FAILED !!!!
*** ERROR # 8030 ***
Request for more memory failed with data block name: lgnelshl.
EXCEEDED AVAILABLE SYSTEM MEMORY. Dynamic memory allocation failure.
It is possible that fixed memory run may succeed (option fixlen=X).
**** Error 8030 in datamr() during 'insert' operation.
Data block name 'lgnelshl'.
Current memory allocation 1883 MB,
Unused memory 1 MB,
Number of blocks: 163 used, 1 free.
Need at least 1218 MB free (1218 MB more than allocated).
************************************************************************
A fatal error has been detected during input processing:
*** ERROR # 8030 ***

*** Run terminated because of error(s) in the input data.
I changed the “memory options” from “memory default” to “upper limit in Mb (= 4000)”.
Is it a hardware problem or is there an option to fix that error?
Thanks a lot in advance!

Hi Sven,
Looks like your machine in sufficient RAM to run the simulation.
can you add the below card and run again?
PARAM, HASHASSM, YES
It would be better to run the job on a machine which has sufficient RAM for the job to run.

Hi Prakash Pagadala,
how can I add the card?
I changed the upper limit to 1880 mb. Now I got another error massage:
WARNING:
The amount of memory that has been allocated is 3964 MB,
which is less than the required 11579 MB for completing the run,
using the minimum core processing in the solver.

A fatal error has been detected during input processing:
*** ERROR # 7007 ***
The run failed because automatic memory expansion has failed.
Currently allocated working storage is 3964 MB.
Automatic expansion failed to expand to 11579 MB.
The failed amount is the minimum required memory to complete the run.
Please verify whether the system has enough memory and rerun the problem.

In order to add PARAM, HASHASSM, YES,
Go to >> Analysis page>> Control Cards>> PARAM and find HASHASSM>> YES

Hello, I have the same problem and this option did not solve it
