Mesh size with ICEM

Dear Friends,
I have a problem with ICEM probably with mesh size. I generate hexa mesh with my code and write a output file in to tecplot format. then, I am uploading it in to ICEM using import grid, tecplot format option. When I try to output to CFX in ICEM, I am getting a error message says that "couldn't fork child process: not enough memory" The size of the grid file is 775MB. Single domain contains 8,516,784 nodes and 8,670,173 hexa elements. I am working with Workbench which came along with CFX11, 64bit version. My system configuration: 64bit, Redhat Linux, 8Gb ram. Yes, I read previous discussions and accoding to them I am somewhere near to the limit with 8GB ram, but all discussions, atleast what I found, were about 32bit machine. One more thing is that I am planning to use LES model to simulate turbulent flow. SO, could any one suggest me how much memory I may need to handle this grid? and for simulation? Thank you very much. Any comment would greatlly help to me. Thanks in advance. I have tested with grid upto 2.7GB elements and ICEM and CFX with LES, working fine! Regards, Subba |
