New question #697783 on Yade: https://answers.launchpad.net/yade/+question/697783
Hello, I recently added periodic boundaries to my simulation, in which I have a granular flow on an inclined plane. For this reason I have a reservoir that is filled with spheres so my incoming flow is steady. Previously I used the following boxfactory command on the engines to generate spheres as observed here: BoxFactory(maxParticles=-1,center=(lr/2,0,(hr+hc)/2),extents=(lr/2,wc/2,(hc-hr)/2),rMin=d-disp,rMax=d+disp,vMin=0.5,vMax=0.5,vAngle=0,massFlowRate=1000,normal=(0,0,-1),materialId=sphereMat,stopIfFailed=False,silent=True,maxAttempt=3,label='BoxFact') Yet I obtain the following error: In [1]: <FATAL ERROR> ThreadRunner:35 void yade::ThreadRunner::run(): Exception occured: InsertionSortCollider::probeBoundingVolume: handling periodic boundary not implemented. I skipped this problem by creating a function that checks if the reservoir is getting empty every few steps, if it's empty I would manually add more. However, since I need to ensure a constant flow I need to add a huge quantity of spheres(Otherwise this would influence the results), making the script very inefficient. Based on this, does an alternative to this command exists that could work in periodic conditions? Thank you very much in advance for any help or suggestions that could exist! If it helps, I assume my current version of yadedaily wouldn't be a problem.
