9mill Mesh not running (doesn't start iterating) in Fluent 19.2 but does in CFX 19.2

Hi everyone,


I try to run a simulation on my university's PC using SST SIMPLE in Fluent 19.2. However, when I start the simulation nothing happens. I assume this is due to insufficient memory but when I start the same simulation in CFX it does run. On another machine at uni with Fluent 19.1 the simulation does run fine though. The machine has 8 cores but the rest of the specs are the same as for the other computer (32GB RAM, 3.4Ghz, 64 bit). Can someone explain to me why I can run the same mesh in CFX but not in Fluent please? Is this a version issue?


Thank you very much in advance for your help.
