Model comparisons for tissue collisions

		Model
		OS	VT	VM
	Low	Repulsion: High interface variability after 40 h (OS), possible mixing of populations after collision and tissue tears	Unbounded: High interface variability after 40 h (VT), interface present for all times, tissues grow towards boundaries	Smooth: Low interface variability after 40 h (VM), although a small number of simulations have high interface variability
Boundary resolution	Default	Short-range: Moderate interface variability after 40 h (OS)	Bounded: Moderate interface variability after 40 h (VT), quick closure time (VT)	Default: Low interface variability after 40 h (VM), quickest collision time (VM)
	High	Long-range: Low interface variability after 40 h (OS), slowest collision time (OS)	Ghost nodes: High interface variability after 40 h (VT), cells move far away from reflective boundaries prior to collision	Curved: Low interface variability after 40 h (VM), slowest collision time (VM)
