how to calculate the total volume of particles after deformation?
Hi Dion,
Can I know how to get the total volume of particles after they are deformed?
I think there are some intersections between particles? Am I right?

Hi Qiang,
Like most DEM codes, ESyS-Particle uses a soft contact model. Particles are allowed to overlap and the repulsive force between particles is a function of the overlap distance. The particles themselves remain spherical so the total volume of the particles is always the same regardless of the deformation.
I presume what you wish to calculate is the total volume of the space containing the particles once deformed. This can be obtained via a Runnable during simulations using the LsmMpi.
minPt = Vec3(0,0,0)
maxPt = Vec3(0,0,0)
sim.getCurMinMa
print minPt, maxPt
This method will only be accurate if the deformed volume of the particle assembly is a rectangular prism.
I hope this helps.
Cheers,
Dion
