Alpha95 New Member Alpha Join Date: Sep 2016 Posts: 1 Rep Power: 0	I have a concentric two circle mesh which is 2D. The diameter ratio is 1:300. Mesh gets finer and finer going from the outer circle to the inner one. I am trying to run a gas-solid DDPM simulation. But when particles get close to the central circle, their concentration drops to zero suddenly. I cannot tell why is it happening. Can anyone help me out?
