Tiny particles don't react with the wall
Hi,
I have a sand model with extral tiny particles among the pore space of the sample, and I use this model for triaxial compression test. The boundary condition is simulated by six rigid walls (use walls=aabbWalls
However, I found that at the end of the simulation (where axial strain = 40%), many tiny particles stay at their original places, which means that these tiny particles didn't react with the boundary wall during the simulation, the example figure could be find at [1].
I guessed it is that there was no contact detection between these tiny particles and the top wall so that these particles passed through the top wall. Then I set the timestepSafetyC
My questions are: (1) The higher the timestepSafetyC
Thanks very much!
