Insufficient virtual memory

sammi

Dear Sir,

We have just installed an additional of 2GB Ram, that is now we have a total of 4GB Ram, for a computer in order to speed up the CFD modelling time and enlarge the capacity of the model. The number of grids is about 1.8 millions and the domain size is about 2250*2000*600. However, a message "Insufficient virtual memory" always appears and told us to increase the number of EARTH in cham.ini. We followed the step and when we increase the number up to 210000000, and start the model again, a nimmediately error message "insufficient virtual memory" comes out. It seems that we have reached the limit. As such, could you advise us how to fix this problem?

How can we increase the memory as we have sufficient physical Ram? How can we increase the size of F-array except using cham.ini? Why there is a limit for EARTH in cham.ini? Can this problem be solved?
