Grid size along (r, θ, z) orientations, denoted as Δr, rΔθ, Δz, for each layer of the esophagus in the reference configuration. Note that the grid size in circumferential orientation rΔθ for each layer should be understood as an average value, since the coordinate r increases from the inner surface to the outer surface.
| Grid size (0.1mm) | IM | OM | IF | CM | LM |
|---|---|---|---|---|---|
| Δr | 2 | 4 | 3 | 3 | 2 |
| rΔθ | 0.5 | 2 | 1.9 | 2.2 | 2.5 |
| Δz | 4 | 8 | 8 | 8 | 8 |
