I recently updated Fluent from 2019 R2 to 2021 R2 as the new supercomputer in our school only supports the latest version.
I also update my case as it can be run by Fluent 2021 R2. I tried 10 cores parallelization in my local machine and it works perfectly. When I upload it to the supercomputer and run with 128 cores, it returns errors like these:March 2, 2022 at 12:02 pmRobAnsys EmployeeStaff are not permitted to open attachments, please re-post the log (if you need a couple of posts that's fine).

The file is fine when I run it on my local machine using the same command, it works perfectly.
I also forward this issue to the staff of the supercomputer team and wait for their reply.
March 2, 2022 at 2:16 pmRobAnsys EmployeeNot sure then. Looking in more detail 800k cells won't scale all that well beyond 8-16 cores depending on physics as the data transfer cost can outweigh benefit of the extra cores.
