Question #277328 on Yade changed: https://answers.launchpad.net/yade/+question/277328
Description changed to: Hi all. I'm a new user of YADE and I'm currently trying to model an avalanche down a slope of variable angle (pi/6 - pi/3). I'm currently using yade.pack.randomDensePack to generate a box of particles to slide down the slope. However, I want to generate a wedge that matches the angle of the slope, essentially a triangular prism with the triangle being a vertical edge, a horizontal edge, and the diagonal edge, extended uniformly across the width of the ramp. I can't figure out how to do this using the existing tools. Here is the existing code that I'm using to generate the box. pred=pack.inAlignedBox((-.1,-.05,-.1),(.1,.05,0)) SpherePack=pack.randomDensePack(pred,spheresInCell=2000,radius=.005,rRelFuzz=0,color=(0,0,1),material="sand",returnSpherePack=True) SpherePack.toSimulation() I thought I could achieve the desired result by subtracting another inAlignedBox from the predicate like this... pred=pack.inAlignedBox((-.1,-.05,-.1),(.1,.05,0))-pack.inAlignedBox((-.1,-.05,-.1),(.1,.05,0),orientation=Quaternion((1,0,0),pi/4)) ...or something similar, but it doesn't work. Please let me know what the easiest way to generate this triangular wedge predicate is. I'm probably missing something very obvious... :p -- 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 : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
