memory problem

Hi,

You can either reduce the number of modes on EIGRL card or go to control cards>> PARAM>>NUMEG and specify a number higher than 1000 

Thank you

I changed  number of modes on EIGRL from 6 to 3.

set param NUMEG to 6000

but same error happened. 

 *** ERROR # 381 ***
 Allocated working storage insufficient.
 Available memory = 2157 MB.
 Required memory = 3546 MB.
 Number of vectors in modal space = 5625.
 Number of eigenvectors = 3.
 Specifying number of modes in EIGRL card of modal subcase may solve 
 this issue. Or, set param NUMEG to a value higher than the number of
 vectors in modal space.

Hi @naoki

Is it possible to share the model file?

Please use the file transfer link in my signature to share the model file
 

Hi,

Can you add SYSTETTING(MINLEN=5000) and check if that helps at your end?

I am able to run the model on my machine with MINLEN of 5000

<?xml version="1.0" encoding="UTF-8"?>

I cannot find MINLEN in SYSSETTING card.

So where should I see? same as OS_RAM_INIT?

If I change memory size,  Required memory is increasing.

 Available memory = 4820 MB.
 Required memory = 6530 MB.
 Number of vectors in modal space = 7636.
 Number of eigenvectors = 6.

@naoki: How about your hardware? RAM? How many nodes/elems?

You can add MINLEN in .fem file. Open the .fem file in any text editor and add the same. I will share the file with you for reference. 

Hello, Prakash san

It could be solved when I added MINLEN=5000 in .fem file directly.

Thank you so much!
