Hi,

At this time I try to setup the following configuration:

Workstation with 2 NIC's:
- NIC-1 --> VPN to license server with ip-range 172.16.200.0/24
- NIC-2 --> IP-range 10.224.59.0/24 to communicate with PBS Pro Scheduler

I want Fluent to retrieve the license from the 172.16.200.0 network and then submit its job to 10.224.59.4 (where the PBS scheduler resides).
ANSYS Fluent is used in an interactive mode so the scheduler is reporting back to Fluent continuously.
What happens is when Fluent is started, it adds the following parameter to the PBS command:
LM_PBS_ARGS=LM_PBS_ARGS=-r18.0.0 3d -pdefault -mpi=intel -node -t30 -mport 172.16.200.58:10.224.59.4:60367:0 -g ,PBS_ENABLED=1"

As far as I understand is the mport parameter used for setting up communication between the headnode and the Fluent workstation. (172.16.200.58 is the workstation).
However, communication between these two networks is not possible (at least not without setting up routing etc.etc.).

I really would like to know if it is possible to modify the LM_PBS_ARGS parameter because the mport should be 10.224.59.7:10.224.57.4 instead of 172.16.200.58:10.224.59.4

Also, Is it possible to provide a parameter to Ansys Fluent 18.0 (via the Fluent Launcher) so Fluent uses a specific network interface for communications?
