Use DPM Domain enables the use of a separate computational domain for particle tracking, which improves load balancing and scalability at the expense of some additional memory overhead. But DPM Domain option has below limitations. if the Eulerian Wall Film model is enabled if the PDF Transport model is enabled if the case has a dynamic zone if the case has a sliding interface if the case includes non-zonal surface injections (that is, injections that have positions defined through surfaces that are not zone surfaces) If the Use DPM Domain option is enabled in such cases, ANSYS Fluent will issue a message warning that the DPM Domain is suppressed. You can avoid this message by disabling the Use DPM Domain option in the Parallel tab of the Discrete Phase Model dialog box.
