Abaqus Subroutine high necessity of RAM.

[Levent-10]

Hi all, I have a model with 1.2 million elements. And I run sigini subroutine to establish initial stress state. I use 1.2 million do loops to check element numbers and assign sigma(ntens) based on element numbers. Because of high necessity of memory I get a 'error in connection to analysis' message and job terminates. I run same model with sigini code only for 8160 do loops and it completed successfully with the message that 'memory allocation increased to 1610 mb' so the problem is lack of memory. I tried to use 640 gb disk space to use as virtual memory. But abaqus doesn't use that virtual memory. Anybody, any help ? Please.
