| contents | We study the dependence of alignment and confinement on the aggregate morphology of self-aligning soft disks in a planer box geometry confined along y direction. We show that the wall accumulation of aggregates becomes non-uniform upon increase in alignment strength and decrease in box width. The height of these structures is found to be a non-monotonic function of alignment strength. Additionally, we identify two distinct categories of wall aggregates: layered and non-layered structures each exhibiting distinct local structural properties. For non-layered structures, local properties stay nearly constant as we move away from the boundary, while for layered structures, they increase with distance from the boundary. Our analysis shows that active pressure difference is a useful indicator for different aggregate morphologies and the peaks in the pressure curve are indicative of the average and minimum height of the structure. |
