Hi everyone,

I know that the syntax for Rocky in batch mode is something like this 

Rocky --simulate "project.rocky" --resume=0 --use-gpu=1

but what about when you want to assign some cpu cores (40 cores for example) to Fluent and use one GPU for Rocky in a two way coupling?

Helo mkhademi,

 

You should assign CPU cores for the Fluent through Rocky interface in CFD Coupling | 2-Way | Fluent | Solver Processes.

This can be done via API:PrePost with a script, that you can run to finish your setup and then simulate your (existing) project, both in batch mode. 

 

FOR EXAMPLE

 

Rocky.exe --script "script_name.py" --headless "project.rocky"
Rocky.exe --simulate "project.rocky" --resume=0 --use-gpu=1

 

You may check on Section 7.4.4–Use the Command Line to Process a Simulation–of the User Manual (that you can access from Rocky Menu | Help | Manuals | User Manuals) for more information. 

Kind regards, 

Lucas
