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)... |
