Hi all! 

I'm trying to run a System Coupling simulation (Transient Structural + Fluid Flow) on a Linux Cluster but unfortunately, the coupling between the two solvers is stopped when the simulation is launched. The error that I received is: 

"(DP 0) Could not connect to System Coupling Service on 56623@linux-cluster-name." 

The Fluent version that I'm using is 21R2 but I also tried on 22R1, 23R2, and 24R1. The same versions on Windows work. Furthermore, 19R3 version works on Linux but unfortunately I'm unable to install that version on the Linux cluster on which I'm supposed to run the calculations due to incompatibilities between the version and the cluster OS. Is there something to be set regarding the licenses? I saw other posts on the Forum regarding this matter but none of them actually gives a clear solution. Thanks in advance to anyone who will help!
