You can count me as a newbie, so sorry for possible stpd questions.

I have a well posed case file. I want to solve it in my new machine.
intel 8core processor
6gb ram
win xp 32bit

How am I going to solve it with 8cores?

I have read so many threads about batch codes, but all of them are missing a point:

Where to write these batch codes?

I tried this, but it didn't work:
start>run>cmd.exe
c:\Fluent.Inc\ntbin\ntx86\fluent.exe -r6.3.26 -t8

Fluent opened and asked for version
version>3ddp

But when I open task manager>performance I see that %13 of processor is in use with only one processor fully working.

Then I tried this, but didn't work either:
c:\Fluent.Inc\ntbin\ntx86\fluent.exe -job
c:\Fluent.Inc\ntbin\ntx86\fluent -job
and got error message.

Please help, I want to learn this thing.

Increasing number of processors in small problems doesn't necessarily means increased performance... Rather use less procs!

My largest case was 1.5m. It works great wiith 2 proc (98%). What happens if u lower the processor number?

try running fluent -3dp -t8

ok, i found the problem with the help of one of my friends.
i didn't set environment at the beginning, so fluent -3ddp -t8(or -t4, etc) didn't work and gave error.

now it runs well.

I have 1.4m elements... it does not converge easily, so I think i will try reynold equations(7 eqns)...
