With such a variety of successful and well tested methods, one is tempted to ask why there is a need to consider yet another method.作者: 擴(kuò)大 時間: 2025-3-22 11:00 作者: 有機體 時間: 2025-3-22 14:00 作者: 聚集 時間: 2025-3-22 19:43 作者: beta-carotene 時間: 2025-3-23 00:21

We will quickly realize that what may have seemed unnecessarily complicated in the one-dimensional case now enables us to expand the formulation to multiple dimensions with only minor changes.作者: 凝結(jié)劑 時間: 2025-3-23 17:47 作者: 闡釋 時間: 2025-3-23 21:44

Among these are the widely used finite difference, finite element, and finite volume methods, which are all techniques used to derive discrete representations of the spatial derivative operators.
