Looks like you are running into a 32 bit OS memory addressing limitation. Use a 64 bit OS e.g. Linux 64 bit or windows 64 bit.

Re: i need your real help
 

Hi This is caused if the virtual memory is low. Try increasing the paging file size of the directory in which the fluent is installed.

Yup out of memory. Use 64 bit exec with OS and h/w. Otherwise run in parallel and use shared memory. Or use Linux which can address more memory. Or cut down cell count using hexcore or use seg solver etc to reduce memory requirements.
