mass or volume of particles
a fundamental question! my examiner has asked me how the mass and volume of the particle are calculated in Dualsphysics. I could not find this info in the manual. Now, is the mass assigned to each particle? if yes, what's its value? or no, the volume of the particle is assigned to it and the mass is calculated based on volume and density? if this is the case, what is the formula for the volume of particles?
