Hello, I’ve recently been playing around with the demo that comes coupled with the FleX repo in order to simulate dry sand particles.
Something I have noticed is that even though I set the the friction properties as needed, the “sand” particles keep spreading out slowly and never achieve the expected angle of repose.
According to: Angle of repose - Wikipedia the angle is based only on the static friction coefficient.
I have set values in the range of 10-400 for staticFriction, dynamicFriction and particleFriction but they particles still spread out slowly and never seem to come to a rest.
I am still fairly new to FleX and was wondering if anyone can give some insight as to why this might be happening and possible steps moving forward.
A temporary solution was to set the sleepThreshold param to fix the particles when they are moving slow.
