More technical details:

All computer are windows based.

Licence server is running Ansys 2024R1 licence server it’s a windows server in an ESX VM.  Port 1055,1056,2325 are open

First machine which have A100 GPU had previous version of Ansys/Rocky (2022R2, 2023R1 and R2) but is now with 2024R1.  It’s a windows server used in TS mode (remote desktop).

Others machines with GTX GPU and without GPU are clean 2024R1 install (windows 10 and windows 11).

Licensing show correctly (Rocky_Prepos, Rocky_HPC, …) we have 25/250 Research/Teaching Multiphysics licence downloaded from portal and installed.

Ansys Fluent (2-way coupling) is running fine with any number of CPU/Core.  Ansys Rocky is working fine everywhere with 0 to 4 CPU, complaining about HPC licence when trying to use more than 4 CPU.  Rocky see the GPUs (A100 and RTX) correctly, lunch with the A100 correctly but complain about no GPU licence on the machines with RTX.

So it’s 1-Limitation to 4CPU only for Rocky and 2-Unable to use GPU licence other that on the A100 that are problematics.

Ok for #1 I still have no clues.. Got some other computer to use GPU, they had previous version of ansys installed.. could it be some licence config issue?

And for #2 It's really a licence server communication issue, Software checkout Rocky_prepost and Rocky_solver correctly but return an error for Rocky_HPC
