“…For a general introduction and overview, see Sethian [21]. For details about projection methods and their coupling to level set methods, see Almgren et al [2,3], Bell et al [4], Bell and Marcus [5], Chang et al [7], Chorin [8], Puckett et al [16], Sussman and Smereka [24], Sussman et al [23,25], and Zhu and Sethian [30]. On the viscoelastic side, in recent years there has been considerable interest in projection-type schemes for viscoelastic flow, see, for example, Trebotich et.…”
