Hello,

I'm trying to run ansys in batch mode in a cluster and I am kind of new to it. Can someone help me on how to run ansys on multiple nodes. I use arc cluster from my university and I use "fluent -g 3ddp" to run ansys in batch mode . I can us "-t64" to specify number of cores. But as one node has a maximum of 64 cores I could never run it on multiple nodes. So I would appreciate if someone can help me with the command for running fluent on multiple nodes.

Since you already have an ARC cluster setup, then you can use Ansys RSM to run on multiple computers simply by launching Fluent through Workbench and setting solution to be sent to Ansys RSM using the number of cores you need to use.

please refer to these links below

Firstly configure RSM client

I am assuming you are familiar with starting workbench 

add a desired Anslysis system

I cannot acces the links you provided as it is asking me for customer number and I don't have one as I am using ansys from university licence.

I want to run fluent simulation on multiple nodes so it can run faster. I am using " fluent -g 3ddp -t500 -cnf=hosts.txt " command to run it. I also tried changing number of solver processers fluent launcher and by giving the machine names in parallel settings. But It's not working properly and I don't understand why. Can you give me an insight on that?
