Help!!!Thank you!!!
 

I'm a student. I had to use fluent to simulate heat loss. but my windows computer is too weak under millions of grid. Therefore, I got an account for using the cluster. but it is linux. I installed the software in the cluster under ssh2. the directory is:/home/luo/Fluent.Inc
I modified the .bash_profile file. here is the last sentences:
export PATH=$PATh:./Fluent.Inc/bin
unset USERNAME
export "FLUENT_ARCH=lnamd64"
DISPLAY=(my windows ip address):0.0
export DISPLAY

when i typed: ./Fluent.Inc/bin/fluent -g 3d
/home/luo/Fluent.Inc/fluent6.3.26/bin/fluent -r6.3.26 -g 3d
/home/luo/Fluent.Inc/fluent6.3.26/cortex/lnamd64/cortex.3.7.3 -f fluent -g (fluent "3d -alnamd64 -r6.3.26 -path/home/luo/Fluent.Inc")

I have installed the exceed. therefore, I typed:./Fluent.Inc/bin/fluent
[luo@node11 ~]$ ./Fluent.Inc/bin/fluent
/home/luo/Fluent.Inc/fluent6.3.26/bin/fluent -r6.3.26
/home/luo/Fluent.Inc/fluent6.3.26/cortex/lnamd64/cortex.3.7.3 -f fluent (fluent " -alnamd64 -r6.3.26 -path/home/luo/Fluent.Inc")
Error: can't open display.
fluent: error: couldn't initialize interface.


so, what's the reason? does anyone give me some advices? thank you!

try to type:
>./Fluent.Inc/bin/fluent 3d -driver x11 &

you may also try to start fluent with "-g" option.
This will turn off the graphic interface. If you are running your Fluent from remote computer that is operating on Windows this option might by crucial.

good luck.

sorry, it didn't work.

I assume you are SSH'ing into the cluster with an ssh client like PuTTY from Windows? You need to make sure you enable X11 forwarding for the GUI to display. (In PuTTY, this option is in Connection-SSH-X11) I realize you said you were a student and you posted this message back in June and the semester is likely over, but hopefully this will help someone nonetheless.
