We amended the following sentences of the discussion: “These differences may be due to the fact that we use a shallow domain (7.5 microns) to reduce the simulation run time, which may cause the pattern to be “squashed” as the domain ceiling prevents ridges from growing vertically” “Restricting the virtual trichomes such that they may only glide when in contact with the substratum or another trichome may promote further aggregation of the trichomes from streams into ridges, as a trichome would be less likely to successfully break away from a stream because it would lose much of its propulsive force as it lost contact with neighboring trichomes and/or the substratum.”
The authors mention in the discussion that they may get stronger results for a deeper system, or for trichomes that may only glide freely near a surface or other trichome. In terms of the understanding gained from the modelling/simulations, how would these lead to qualitative changes in the observed patterns?
