Obtaining the Current Mass of Particles while Performing an Unsteady DPM Simulation

How to obtain the current mass of particles in the domain while performing an unsteady DPM simulation?

Mass of particles in the domain at a current time-step or iteration, when using unsteady DPM can be obtained using either of the following methods:
1. From Report Definitions > New > DPM Report > Mass in Domain
2. Using Reports > Discrete Phase > Summary
3. Writing a particle history file from Particle Tracks

Details on using these options have been discussed in the attached document.
