I guess yes for this case. If to use iterPeriod, virtPeriod or realPeriod depends always on specific context. 3. see above, it is always different.

Although Jan may keep replying the questions because he is super-nice, it's now clearly not about computing total mass.

It's very confusing for someone to not distinguish what's python and what's Yade, and I smell it could be your case. :) Regards Bruno Side note: consider indenting with tabs or four spaces (at least), most text editors can do that for you.

As a result of this simulation I need to obtain the weight or mass of the particles that remain within each cylinder. In the Yade documentation that I have consulted, I saw that the state.mass function fulfills this need, but since I do not have enough domain in this programming language, I needed to know if anyone has any example of how to use this code or if they have more information ... I appreciate your collaboration The code I am using is as follows: postscript: the code comments are in Spanish (Latin) from yade import pack, plot #Altura de caida del material hc=0 #EQUIPO #coordenadas centro x=0 y=0 z=0 #coordenadas extension f=0.45 a=0.50 h=1 #estrutura del equipo de pluviacion O.bodies.append(geom.facetBox((x,y,z),(f,a,(h+hc)),wallMask=31,wire=True)) #Mallas #O.bodies.append(utils.wall((0,0,(.2+hc)),axis=2,color=(1,0.945,0.078),sense=-1)) #(0,0,(.2+hc)),axis=2,color(1,0.945,0.078),sense=0)) #O.bodies.append(utils.wall((0,0,.2),axis=2,sense=0)) #PROBETA #Radio radius=0.05 #Altura de la probeta height=0.1 #Probeta 1 #Coordenadas centro xp1=0.1 yp1=0 zp1=1 O.bodies.append(geom.facetCylinder((xp1,yp1,(-zp1-hc+(height/2))), radius=radius, height=height, fixed=True, wallMask=6, color=(0.933,0.090,.894), wire=False)) #Probeta 2 #Coordenadas centro xp2=0.1 yp2=0 zp2=1 O.bodies.append(geom.facetCylinder((-xp2,yp2,(-zp2-hc+(height/2))), radius=radius, height=height, fixed=True, wallMask=6, color=(0,0,1), wire=False)) #coordenadas perimetro de particulas #esquina inferior xi=0.225 yi=0.225 zi=0.2 #esquina superior xs=0.225 ys=0.25 zs=0.5 #porosidad p=0.903 #tamices #los diametrso y los porcentajes acumulados siempre se deben ubicar de menor a mayor #por cada t debe haber un p #Diametro de la abertura de tamices psdSizes t1=0.008 t2=0.015 t3=0.030 t4=0.085 t5=0.200 t6=0.475 #Porcentajes retenidos del material psdCumm p1=0 p2=0.002 p3=0.111 p4=0.889 p5=0.9994 p6=1 #Material #angulo de friccion angulo=radians(36) #radianes #densidad del material densidad=1418 #(kg/m3) #Modulo de Young young=(1e8) #Pa #Poisson poisson=0.5 #contenidod de vacios porosidad=0.9 #Algoritmo YADE para el material snd=O.materials.append(FrictMat(young=young,frictionAngle=radians(angulo),density=densidad, #label="SndG" )) #Algoritmo YADE para el cuerpo de las esferas sp=pack.SpherePack() sp.makeCloud((xi,-yi,(zi+hc)), (-xs,ys,(zs+hc)), porosity=porosidad, psdSizes=[t1,t2,t3,t4,t5,t6], psdCumm=[p1,p2,p3,p4,p5,p6], distributeMass=False) sp.toSimulation(material=snd,color=(0.882,0.866,0.839)) O.engines=[ ForceResetter(), InsertionSortCollider([Bo1_Sphere_Aabb(), Bo1_Facet_Aabb(), Bo1_Cylinder_Aabb(), Bo1_Wall_Aabb() ]), InteractionLoop( # handle sphere+sphere and facet+sphere collisions [Ig2_Sphere_Sphere_ScGeom(),Ig2_Facet_Sphere_ScGeom(),Ig2_Wall_Sphere_ScGeom()], [Ip2_FrictMat_FrictMat_FrictPhys()], [Law2_ScGeom_FrictPhys_CundallStrack()] ), #GravityEngine(gravity=(0,0,-9.81)), NewtonIntegrator(gravity=(0,0,-9.81),damping=0.4), PyRunner() ] O.dt=PWaveTimeStep() -- You received this question notification because your team yade-users is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
[Yade-users] [Question #688837]: calculate the mass of the particles
New question #688837 on Yade: https://answers.launchpad.net/yade/+question/688837 I have generated a code for the simulation of the sand free fall. This simulation consists in dropping the spheres that simulate the sand as a result of the material, so that they are deposited inside two cylindrical containers. As a result of this simulation I need to obtain the weight or mass of the particles that remain within each cylinder. In the Yade documentation that I have consulted, I saw that the state.mass function fulfills this need, but since I do not have enough domain in this programming language, I needed to know if anyone has any example of how to use this code or if they have more information ...
