Hi, I'm working with DPM injections.
1) Exactly, used surface case, and i chose inlet where 4018 surfaces. But i can not control the number of particles. I'm using unsteady DPM.
My questions:
How i can control the number of particle?
2) When i look to summary there are shown that
Total number of parcels : 120458
Total number of particles : 4.855374e-06
How number of particle could be non integer number?
What is parcel mean?
What is the relationsheap between particle and parcel
3) When i look to the Particle Mass Concentration there are shown results in -15 th degree.
