hejhej,

i need the forces on a specific patch and therefor i use the function forces. it works fine when running on a single machine, but on cluster it stops writing the results to the forces file in /postProcessing/forces/ but the Terminal output still works
can someone please help me on this issue?

my controlDict:

the answer to this problem was the umask of the slave-machines. the data they wrote wasnt readable by the master-computer. i changed it to 000 globaly on all slaves
