why does fine Particles penetrate the geometry?
My name is Ahmed Rami, I am a student at Universiti Teknologi PETRONAS. while I was using Altair EDEM to do some simulations I faced a problem I couldn't solve by myself. For some reason while doing the simulation I noticed that some of the particles are penetrating the geometry and I have no idea on why is that happening.
I tried increasing the shear modulus and reducing the time step as someone suggested and it did stop the particles with 0.005 Meters physical radius from penetrating the geometry but when dealing with fine sand which has a physical radius of 0.0002 Meters the particles just penetrate the geometry as if there was no geometry at all.
Note: Im using
- steel as a geometry material with a solid density of (8050 kg/m^3)
- sand as a particle material with a solid density of (2600 kg/m^3)
I also included some pictures of the properties of both sand and steel.
