I tried to erase some particles, it was done without any problem. but after finishing the simulation, as soon as I tried to run more iterations, it showed segmentation fault and quit yade. The length of O.bodies is similar to The one before erasing.(Does not change after erasing) you can see my question in: https://answers.launchpad.net/yade/+question/668274 I'm using Ubuntu 14.04 LTS and yadedaily version: 2018.02b-85-f861843~trusty And here is my script: # -*- coding: utf-8 -*- from yade import pack, plot young=1e8 compFricDegree = 5 finalFricDegree = 35 mn,mx=Vector3(0,0,0),Vector3(.005,.005,.005) O.materials.append(FrictMat(young=young,poisson=0.5,frictionAngle=radians(compFricDegree),density=2600,label='spheres')) O.materials.append(FrictMat(young=young,poisson=0.5,frictionAngle=0,density=0,label='walls')) walls=aabbWalls([mn,mx],thickness=0,material='walls') wallIds=O.bodies.append(walls) psdSizes=[.00001,.00006,.00008,.0002,.0004,.0005,.0008,.001] psdCumm=[0,.0175,.025,.4,.5,.7,.85,1] sp=pack.SpherePack() sp.makeCloud(mn,mx,psdSizes=psdSizes,psdCumm=psdCumm,distributeMass=True,num=500) sp.toSimulation(material='spheres') triax=TriaxialStressController( maxMultiplier=1.001, finalMaxMultiplier=1.0001, thickness = 0, stressMask = 7, internalCompaction=True, ) newton=NewtonIntegrator(damping=0.2) O.engines=[ ForceResetter(), InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Box_Aabb()]), InteractionLoop( [Ig2_Sphere_Sphere_ScGeom(),Ig2_Box_Sphere_ScGeom()], [Ip2_FrictMat_FrictMat_FrictPhys()], [Law2_ScGeom_FrictPhys_CundallStrack()],label="iloop" ), triax, newton, ] O.dt=PWaveTimeStep() triax.goal1=triax.goal2=triax.goal3=-10000 while 1: O.run(1000,True) unb=unbalancedForce() print 'porosity', triax.porosity if unb<0.01 and abs(-10000-triax.meanStress)/10000<.01: break bodiesToBeDeleted=[] for b in O.bodies: if b.id in range(6): continue else: if b.state.pos[0]<.002: bodiesToBeDeleted.append(b) for b in bodiesToBeDeleted: O.bodies.erase(b.id) To manage notifications about this bug go to: https://bugs.launchpad.net/yade/+bug/1767601/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : yade-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
