I am seeing some weird\/strange deposition pattern where it seems the particles are lining up along mesh cells (although not sure). This pattern is not observed with DRW model off or DRW model ON for 100 um particles. Why is this occuring? I have turned ON high-resolution tracking and left everything at default.
