Can you help with this question.
If run the 32bit CCM+ in W7/64 I can use a big swap file than the 4 GB limit for 32 bit O.S., this help me with message "Insufficient virtual memory". Itīs correct. Thanks, Marcelo |

Will not help. The error message you are getting says that all physical memory is being used and more virtual memory is necessary. Only two solutions for this - add more physical memory or increase virtual memory (swap space). Be aware that while adding swap space may work, it will slow the analysis down significantly, because now you have I/O to contend with. Your quick option is to decrease the cell size.

I don't think so. 32 bit systems are set up to use only 4 gig memory (XP will only address 3.5 gig). Since you are running a 64 bit version of WINDOWS 7, why not use the 64 bit version of CCM+? It is available from CD-adapco's download site. I have 64 bit WINDOWS 7 and the 64 bit CCM loaded on my laptop. It has 8 gig memory. I just completed a job with 6.1 million cells with no problem. It is easy to install.

@Roberto: Too small Swap file? Then limits windows the virtual space...
32 Bit can only handle 2GB per thread - run parallel to use more. Mesh per region, split the regions etc. |
