Modeling the grain on the slope

PFC

Dear All,

I’m trying to make a single slope model to see the displacement that occurs on the slope. I have set the gravity value, but the particles from the slope move up.

What can I do to fix this?
Thank you in advance, your help means a lot to me.

@syaniliffa make the gravity negative (-10)

Thanks for the advice, I’ll give it a try

I have tried to set negative gravity, but it still the same :frowning:

The problem here is not the gravity setting. My assumption is large contact forces are present when cycling under gravity that are causing the balls to break their bonds and “shoot” off. Usually, this is a problem with generating the slope assembly and not zeroing out contact forces. I have received your model (PFCsupport@itascacg.com) and will reply accordingly.

Hello sir, can I get your email address? i am also working pfc

Hello @Hussain, if your question concerns PFC you can send it to PFCSupport@itascacg.com. That is the official PFC technical support email and I personally take questions from it, or delegate questions to other engineers at Itasca.

Hello Respected Sir, Greetings from the China University of Geosciences Wuhan.
Sir, I’m a new PFC software seeker, and my research focuses on landslides. I created the geometry for my lab experiment. Sir, I am facing one problem.

  1. The problem is when I run the rock sliding code on my geometry, the clumps move well on inclined surfaces, but when they reach the geometry’s horizontal plate, they move down.
    Sir, I need your assistance and suggestions to resolve this issue and let me know how to fix clump movement in my geometry.
    I hope for your kind consideration and response
