Hello everybody,

I'm experiencing trouble installing Fluent 6.3 on Red Hat 5.5
I always used Fluent on WIndows, now I want to move to Linux, but I have no experience.
This is what I did:

I installed Fluent in the folder /home/Sale/Fluent.
Then I went in the folder /home/Sale/Fluent/Fluent.Inc/bin and I wrote ./fluent
I had this error message:

/home/Sale/Fluent/Fluent.Inc/fluent6.3.26/bin/fluent -r6.3.26
Error: directory /home/Sale/Fluent/Fluent.Inc/fluent6.3.26 does not contain a valid arch.
Set the environment variable FLUENT_ARCH and try again.

After that I wrote:

FLUENT_ARCH=lnia64
an then
export FLUENT_ARCH

At this point if I write ./fluent I obtain:

/home/Sale/Fluent/Fluent.Inc/fluent6.3.26/bin/fluent -r6.3.26
/home/Sale/Fluent/Fluent.Inc/fluent6.3.26/cortex/lnia64/cortex.3.7.3 -f fluent (fluent " -alnia64 -r6.3.26 -path/home/Sale/Fluent/Fluent.Inc")
/home/Sale/Fluent/Fluent.Inc/fluent6.3.26/bin/fluent: line 4668: /home/Sale/Fluent/Fluent.Inc/fluent6.3.26/cortex/lnia64/cortex.3.7.3: cannot execute binary file

Can anyone help?
Is there any applications missing (I just formatted the pc and perhaps there is something still not installed)?

Any advice could be very helpful.

Thanks in advance
Sale

Hi Sale,

I am very interested if you have managed to install Fluent on Red Hat and where you got the installer from.

I have switched to Red Hat and would like to put Fluent on it.

Regards,

Ivan.

Dear Ivan,

I don't know why, but at the end I installed Fluent_install-lnx86-6.3.26.tar instead of Fluent_install-lnia64-6.3.26.tar, even if it is 64 bit platform.
The I set the environment variable in the following way:
FLUENT_ARCH=lnx86
export FLUENT_ARCH

In this way it works.

Regards,
Sale

Hi Sale,

thanks for the information. I have Red Hat 64 bit, so I guess it should work.

One last quick question. To install Fluent, do you just type in the terminal this?

$ Fluent_install-lnx86-6.3.26.tar
$ FLUENT_ARCH=lnx86
$ export FLUENT_ARCH


is that all??

Thanks a lot beforehand.

Regards,

Ivan.

Not exactly.

I did in this way:
I downloaded Fluent_install-lnx86-6.3.26.tar
then I went in the directory where I downloaded the file and I umpacked it:
tar -xf Fluent_install-lnx86-6.3.26.tar
then
./Fluent_install-lnx86-6.3.26.sh
FLUENT_ARCH=lnx86
export FLUENT_ARCH

Now it should work.

Regards

Hi Sale,

sorry to bother you again.

I am quite a newer in Linux and still find it difficult to deal with. I have unzip the .rar file and I can see the .sh file has been created.

However, in that folder, if I type what you say (Fluent_install-lnx86-6.3.26.sh), Linux returns this:

bash: Fluent_install-lnx86-6.3.26.sh command not found

I have also tried this:

./ Fluent_install-lnx86-6.3.26.sh

and Linux returns:

bash: ./: is a directory

Can you guess what I am doing wrong?

:_(

Regards,

Ivan.

Hi Sale,

I have managed at last to do all the operations you have indicated.

However, when I go to ./Fluent.Inc/fluent6.3.26/bin/

and type fluent or fluent -r6.3.26, Linux returns:

bash: fluent: command not found

The thing is I actually can see that the fluent file (or command, or whatever it is) is indeed in /Fluent.Inc/fluent6.3.26/bin/

I am sure I am doing something silly...

Regards,

Ivan.

You have also to di the following:
export PATH=WhereTheFolderIs/Fluent.Inc/bin/:$PATH
and then, if everything is ok:
fluent -driver x11

I am also new to Linux. I am just tring to explain what I did and what worked for me.

Regards,
Sale

Hi Ivan

try ./fluent instead of fluent in bin directory

or try this to work in 3d: ./fluent 3d in bin directory again.

if it says something about FLUENT_ARCH, then type

FLUENT_ARCH=lnx86
export FLUENT_ARCH

now you can usr fluent with ./fluent command
