Hi all,

I am new to Linux and tried to install Fluent on it. I had done everything mentioned in the installation guide and the CFD-online forum as well but I am still unable to run it. For example, I first install the .sh file using sh command then added some lines in the .bash_profile file. I have installed everything in the home directory. But now, when I type fluent in the terminal window it says fluent is not a command.

Can somebody pls help that where am I making a mistake or whats the problem?

Regards

since you get the unknown command, it means that the executable isn t recognized.
Is there a fluent executable under /bin?
I think there is other folders like 2d 2ddp 3d 3ddp
go into one of these folder, and try to call the executable (which is in the folder)

I dont know how Linux shows an executable file, unlike in Windows where it is .exe. But in the bin folder this is the only file avaialble. I will try in other folders as well.
What about liscence file do we need to do something with liscense install or something like that as we did in windows?

I don't have fluent anymore, but I remember I had similar issue
It was just a problem of environment variable
Have you checked here?
How to run fluent in LINUX
Once it is solved, you have to install the Fluent License Manager and to place your license file under /license

you are not supposed to copy and paste the .bash_profile file
It is supposed to be already present under your user folder /home/user_folder, where user_folder is the session you are logged in

try this
/.../Fluent.Inc/fluent-6.x.x/bin/fluent
or
/.../Fluent.Inc/fluent-6.x.x/bin/fluent 3d
where 6.x.x is the fluent release you are trying to run

Hi,

I am able to run fluent 6.3.26 on Linux suvccessfully. But unfortunatley the performance is slower than Windows HPC wich I had previously installed. What could be the reason? And even sometimes the Fluent hangs as well.
