[Yade-users] [Question #631227]: Porosity of a packing with overlapped particles
New question #631227 on Yade: https://answers.launchpad.net/yade/+question/631227 Hi, I defined a function to calculate the porosity of a packing with lots of overlapped particles, because the build-in function "utils.porosity()" always got a negative one. This question (https://answers.launchpad.net/yade/+question/404363) gave me some useful hints. My own function has a serious error, that is my function always got a same porosity whatever the growFactor is. Here is my code segment: from yade import utils from yade import pack from yade import qt mat1 = O.materials.append(FrictMat(young=5.0e7,poisson=0.25,density=2640.0,frictionAngle=radians(18))) pred = pack.inAlignedBox((0,0,0),(0.01,0.01,0.01)) dim = pred.dim() packing = regularHexa(pred, radius=0.0005,gap=0,material=mat1) O.bodies.append(packing) # grow particles in order to get lower porosity growFactor = 1.5 utils.growParticles(growFactor) def overlappedPorosity(totVol,density): totVol = dim[0]*dim[1]*dim[2] mass = sum([b.state.mass for b in O.bodies])*pow(growFactor,-3) return (totVol - mass/density)/totVol print 'The porosity of this packing is:',overlappedPorosity(dim[0]*dim[1]*dim[2],O.materials[0].density) # 3D view and controller try: qt.Controller() qt.View() except: pass In my function, ''mass = sum([b.state.mass for b in O.bodies])*pow(growFactor,-3)'', because after the packing was generated, the radius of each particle in packing was magnified by growFactor using growParticles. Any useful advice will be highly appreciated.
