Hello!
I am getting the following issues with my case, running rans simplefoam. On my local computer everything works but once I run it on a cluster i get the following error which repeats for each processor (1-8):
cannot find file "/parallel_scratch/vb00336/refined_RANS_7/processor3/0/p"

I also get a recomposeParDict., foam warning.

my bash script has decomposepar and recomposepar inside


Any help would be greatly appreciated!

Hello,

You're not providing enough information to get help.
(How to give enough info to get help)

First thing is to check if this file exists:
Code:
cannot find file "/parallel_scratch/vb00336/refined_RANS_7/processor3/0/p
If it does not, check your workflow and log files for each step to see if there is a command failing at some point.

Regards,
Yann

Does your case file have the decomposeParDict file in the system folder?
It looks like this:
