[QUOTE=Paola;322945First, my computer has an architecture: x86_64 (you can see it with "uname -m" command). So I had to set the variable FLUENT_ARCH equal to lnx86...[/QUOTE]
On my home computer:

Code:

uname -m

x86_64
and it is 64-bit system.
I use FLUENT_ARCH=lnamd64
because of FLUENT_ARCH is FLUENT architecture, not architecture of the system!
And u use FLUENT_ARCH=lnx86 because you have x86 fluent package.

Oh! That was why I was all mess up at the begining

Ok, so is it a Fluent with a lnx86 architecture appropiated for my system 64bit?

Thank you, villager!

I think so)
I run Gambit 2.3 x86 with FLUENT_ARCH=lnx86 and Fluent 6.3 with FLUENT_ARCH=lnamd64 on my amd64. I think,if somebody use Intel x64 processors, he must specify FLUENT_ARCH=lnia64.
You can run x86 programms in 64-bit system, but you cant't run 64-bit programms in 32-bit system.

So, when you buying (or downloading) fluent, check its version to be compatible with your computer.

No, lnia64 option is only for Itanium processors, and lnamd64 for both Intel and Amd processors.

This will give you a bunch of files where fluent is installed. Find the one that looks something like: ....../ansys/13.0/v130/fluent/fluent13.0.0/bin/fluent. The last 2 directories "bin/fluent" will be identical. The rest of it may be different depending on your version.

This file bin/fluent is the launcher. The easiest way to launch is by first nothing the path to "bin/fluent", and then typing in the terminal: (substituting your own path for mine)

Code:

cd /apps/ansys/13.0/v130/fluent/fluent13.0.0/bin
./fluent

Thanks. This was really helpful.

Hi There I am using Fluent in Linux and am using .jou file with following commands;

file read-case file name.cas
file read-data file name.dat
file auto-save data-frequency 0
solve update-physical-time
file auto-save data-frequency 100
solve dual-time-iterate 500 50
file write-case end-file name-1.cas
file write-data end-file name-1.dat
exit
yes

There is an error in the above mention code because I could save data files at every 100 intervals.

Can anyone help me with this?
