Hello,

It seems like you are running out of memory. Could that be possible?

Thank you for the reply.
The machine which I am using has 2gb ram 2ghz core2 duo processor.
I will relax the meshing part a bit so that required memory reduces and then shoot it in the Fluent.

You want to run a mesh with 4.5 million cells on a single machine? Reduce it by a factor of 10 to 450000, even this will take a lot of time.

It took me 20G RAM and 8 processors for only 8 millions of cells.
Make a kind of ratio to see the limits of your computer for 4554076 cells.

You require minimum of 12 GB RAM for such a karge number of nodes. Either reduce number of nodes or increase RAM of your machine

You need to limit your number of cells up to 2.5 million... or you need a powerful computer to work on..
