"Continuous Memory" Errors in COSMOS FloWorks 2005

Dave

Hello all,

When solving more than about 500,000 cells, I always get an error similar to the one below--only the numbers change:

"Failed to allocate requested continuous memory block of 101980480 bytes (97.256 MB) due to memory fragmentation! Memory Diagnostic:

Largest Continous Available Memory Block 79755263 bytes (76.061 MB)

Requested Continous Memory Block 101980480 bytes (97.256 MB)"

I'm running a dual-core Athlon 64 4200+, 4GB RAM, latest student edition of Solidworks/Floworks for Windows XP. Solidworks/Floworks doesn't seem capable of using more than 2GB of RAM (even with 3GB Physical Address Extensions enabled in Windows), but that should still be enough to solve a 1 or 2 million cell problem, right?

I'm not a CFD engineer; just an ME student trying to analyze a race car's aerodynamics for a school project. I can't simplify the model much more than it already is.

Any help or advice is appreciated. Thank you.
