Hello all!
Has anyone else run into Fluent taking much longer to solve when using RKE than when using kw-SST?

Typically, I've seen kw-SST and RKE take approximately the same amount of wall time to compute a certain number of iterations. But occasionally I'll have a case where RKE takes roughly 7-8x longer than kw-SST and I'm not exactly sure what the culprit is. For me, this appears to only happen when dealing with wall-resolved meshes (y+ <=1).

These jobs are running on another machine where I am not able to monitor the hardware. However, the cases are not large so the machines should have more than enough horsepower to chug through the job.

This is entirely empirical, but I've had it happen to me a couple of times recently and I'm not able to find anyone else discussing it online. Just wondering if anyone has any insight into this and if it's a known thing due to the model.

Thanks!
