hello,
I am running a simulation of a centrifugal fan for erosion prediction, I calculated the flow field using the sliding mesh method. when I use the discrete phase model (DPM) to trach particles in the domain, particles are tracked only in the absolute reference frame.in fluent manual, I found the following:
-When MRF are used in conjunction with the discrete phase model, the display of particle tracks will not, by default, be meaningful. Similarly, oupled discrete-phase calculations are not meaningful.An alternative approach for particle tracking and coupled discrete-phase calculations with multiple reference frames is to track particles based on absolute velocity instead of relative velocity. To make this change, use the define/models/dpm/ options/track-in-absolute-frame text command. Note that the results may strongly depend on the location of walls inside the multiple reference frame
-Relative particle tracking cannot be used in combination with sliding and moving deforming meshes. If sliding and/or deforming meshes are used with the DPM model, the particles will always be tracked in the absolute frame. Switching to the relative frame is not permitted.

the problem when I track particles they stop in the impeller suction side because the track is in the absolute frame of reference.
please I need your help.
