iFPM_process_ID
give a maximum 16-digit MESHFREE process ID
Default: ID given by computer clock time in seconds
All signal, warnings, and log files carry the
MESHFREE process ID inside of their name. Hence, setting the
iFPM_process_ID will avoid long lists of of these files if not desired.
Note: Changing the process ID during run-time (by
ComputationalSteering) will have no effect.
