error message when running particles
 

I am currently attempting to model particle flow in a multistage compressor, utilizing stage mixing planes between blade rows. Starting from a previously converged solution without particles, I have introduced one-way coupled particles at the inlet and am attempting to run a single iteration to calculate particle tracks. I receive the following error message as soon as partitioning is complete:

ERROR #001100279 has occurred in subroutine ErrAction. Message: Stopped in routine ASS_PT_ROTATION

I can find no reference to this error in the documentation. Any ideas on where this is bombing?
