Fig. 1.

(a) Geometry of the glottal airflow domain: the inlet, outlet and glottal surfaces are shaded, the coordinate origin (at the intersection of the mid-coronal plane, the mid-saggital plane and the VF superior surface) is denoted by ⊗, and axes x_is, x_ml and x_ap are in the inferior–superior, medial–lateral and anterior–posterior directions respectively; (b) geometry of the left half of the solid VF model: surface C_L, line AB, and point X_MC are reference regions expected to participate in contact and adhesion; (c) mid-coronal section showing both pairs of VFs and rigid planes: coordinate axes are offset from the origin for clarity
