randomDensePack in a trapezoidal prism form

Asked by Grace Mejico on 2019-07-31

Good evening everyone,

Actually, im modelling a dry stone retaining wall, and it has the form of a trapezoidal prism. It is possible to way to generate that form for the pack?

As i understood from other questions ,i can see it is possible to make a triangle form.So, I was thinking about create a pack in Parallelepiped and add the triangle wedge form ; in that way, those volumes can make the trapezoidal prism. Is that possible? If there is any script for the pack of trapezoidal prism , i will really grateful if you share it .

Thank you so much, and hopefully i could be clear with my request.

In addition, i would like to ask for any research that includes the information about how many particles are necessary for make the simulation validated and for the calibration.

Thank you in advance! :)

Hello,

>As i understood from other questions

Please link to those questions so we can see what you are referring to.

Generally speaking, you can form a pack into any shape you want (including a horse [1]), so a wedge shape shouldn't be a problem. I don't know if we have the equivalent of inCylinder [2] for a wedge, but you can always rely on inGTSsurface [3] (which is what the horse example uses [4])

>how many particles are necessary for make the simulation validated and for the calibration?

I should warn that this question is likely unanswerable due to its unspecific nature.
