New question #682883 on Yade: https://answers.launchpad.net/yade/+question/682883

Hi, I'd like to calculate the mass content of a group of spheres, as far as I know, we can obtain a mass of one sphere by: O.bodies[id].state.mass I'd like to ask that if we can obtain the mass of a group of spheres like: appending some spheres with a same label, like: O.append(sphere((x1,y1,z1),radius=radius,label="label1")) O.append(sphere((x2,y2,z2),radius=radius,label="label1")) O.append(sphere((x3,y3,z3),radius=radius,label="label2")) O.append(sphere((x4,y4,z4),radius=radius,label="label2")) then we can obtain the total mass of spheres with label1, and label2 respectively? I have tried in Yade, it seems that we can not give each sphere a label, is there any way that we can classify the spheres to different groups so that we can just loop in one group of spheres to calculate the mass?
