floworks ERROR: Not enough memory to continue the calculation

[ziga]

Hey folks,

I'm doing some CFD work with Cosmos FloWorks. I can run simple problems without any issues, but when trying larger, computationally intensive operations, FloWorks generates a memory allocation error after about an hour's worth of calculations.

The actual error:
.........................................................
"Not enough memory to continue the calculation. Failed to allocate requested continuous memory block of 1048576 (1.00MB)"
.........................................................

I've gotten this error on two separate occasions, each time about 1.25GB of memory were in use (total). This is on a quad-core intel system with 3GB of memory RAM , so I'm guessing the issue is a software configuration problem..

Any and all thoughts are greatly appreciated. Thanks!

This has happened before to me as well. I believe windows was unable to reallocate memory usage for the CFD program. To address the issue (which works some of the time), I restarted windows and Solidworks before I set-up the CFD problem. This may all be a problem with memory allocation, Windows and Solidworks (and I'm sure the version of all of those matters too).

That's my best crack at it; however, I'm positive there are some people on this forum who should be able to give the exact explanation of the problem and its solution.

Best of luck!

Regards,

Kyle

A way to free some more memory with Windows is to open boot.ini with notepad or another text editor and locate the line:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

Add /3GB to the line like this

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /3GB /noexecute=optin /fastdetect

The /noexecute=optin and /fastdetect are optional btw.
