Utilizing systematically dierential geometry the paper describes a method which substantially improves results obtained by Yuan et al. (1994), though the same technique is used in both articles. An 8-node isoparametric element with curved boundaries is analysed as an object of dierential geometry. I
We present a new numerical algorithm that aligns a quadrilateral grid with internal alignment curves (IACs). These IACs can be used to delineate internal interfaces, discontinuities in material properties, internal boundaries, or major features of a flow field. The adaptive IAC grid generation algor
