Particles penetrating 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 reason on why is that happening.

    Hi,

    This is usually an indication that either your material is too soft or your timestep is too large. Try either increasing the shear modulus or reducing the timestep. 

    There are other possible reasons but I'd take a look at those first.
