Parallel fluent 4 nodes machine (Quad 6600 SUSE)
 

Hello I have a four processor computer (shared memory) i am trying to run Fluent under linux environment (Suse) but it does not work. I was looking in forums and i did not find any solution. Any help? Thank you all anyway

i use: File -> Run... Versión 2d -pdefault -t4 -path/home/rafa /home/rafa/Fluent.Inc Processes 4 interconnect: Ethernet/Shared memory

and it gives back: (and it stops...)

hi. if you run ./fluent 2d -t4 -pnet it will run four nodes. at least here it works...

Re: Parallel fluent 4 nodes machine (Quad 6600 SUS
 

use updated v6.3.35 which is optimised for multi core machines

Thank you, it worked

problem in license server
 

I am using 4 machine (2x quad core processors each) machine for parallel Fluent 6.3.26. They are on RH Linux. I connect them via ssh and making password less environment. After running parallel the job runs fine but after few thousand iterations it says

connection to license server lost.

For running Fluent I type the following command in the Fluent directory
./fluent 3d -t32 -ssh -cnf=host

where host file contains machine names.
