TL;DR: The generalized advancing layers method is presented here as a method of generating meshes suitable for capturing viscous flow problems and includes several new technical advances allowing it to mesh complex geometric domains that cannot be handled by other techniques.

TL;DR: It is demonstrated that the MOF method provides the most accurate tracking of interfaces, followed by the VOF method with the right material order, while the solutions with VOF using the wrong material order are considerably worse.

TL;DR: Two optimization approaches are described, one which improves the quality of elements as much as possible and the other which improves element quality but also keeps the new mesh as close as possible to the original mesh.

TL;DR: In this article, a fine-scale integrated surface/subsurface thermal hydrology modeling capability is described and demonstrated in proof-of-concept simulations on the tilted open book catchment.

TL;DR: In this article, a non-linear numerical optimization process is used to improve the quality of surface meshes while maintaining the essential characteristics of the discrete surface, and the surface characteristics are preserved by repositioning mesh vertices in a series of element-based local parametric spaces such that the vertices remain on the original discrete surface.
