3.4 Examples of the Proposed Consistent Point-Searching Interpolation Algorithm 71
realistic geological situations (Zhao et al. 1998b, 1999c, Hobbs et al 2000, Gow
et al. 2002, Ord et al. 2002, Schaubs and Zhao 2002, Sorjonen-Ward et al. 2002,
Zhang et al. 2003), where both complicated geometry and material nonhomogene-
ity are considered. Although the consistent point-searching interpolation algorithm
is developed for the unstructured meshes consisting of 4-node bilinear quadrilateral
elements, it can equally be extended to the unstructured meshes consisting of higher
order elements. In the latter case, one has to solve the inverse mapping problem
numerically, instead of analytically.
