Explicit and Implicit MethodsELSEVIERComputational Fluid Dynamics
简单理解,就是把非线性的关系,用无数段微元给准确表达出来;毕竟,绝大多数非线性关系都是无法通过一个函数表达式来直接描述的,因此计算机只能将这条曲线分为无数段微元,在每个微元内按固定的法则进行计算。此时用到的法则,就可以分为显示(Explicit)与隐式(Implicit)两大类型。 (线性问题当然不需要考虑这些。因为...

Explicit and Implicit methods are used in numerical simulations to solve a physical process or a series of changes. You may apply these to many scientific simulations that involve time changes such as big bang, chemical reactions, fusion, even social science models. In mathematical terms, they ...
If f(u) = Au where A is a matrix independent of u then the implicit scheme requires solving the system of equations (I-hA).u(n+1) = u(n) and so a matrix inversion needs to be performed. The main pros and cons of these two methods are that explicit schemes are easy to program...
In contrast, FL and L2 teaching methods like "Audiolingualism ," which held sway during World War II, and more recent "Natural" and "Communicative" approaches, maintained that adult language learning is, like L1 acquisition , implicit. Since language skill is very different from knowledge about...
Whereas bulk simulations (e1/i1) are equivalent for explicit and implicit models, the alignment ofVSCwith respect to the water averageVW(e2/i2) is different, due to the fact that the main electrostatic contribution of the average potential in explicit water—the quadrupole contribution30,31—is...
extracted from a single sequential program. These implicit threads may be defined either statically by the compiler or dynamically by the hardware. In the remainder of this section we consider explicit multithreading. 2 The term context switch is often found in OS literature and textbooks. Unfortunat...
I'm no expert on implicit methods, though, maybe there are clever tricks to circumvent this and make the scaling acceptable. I prefer explicit methods, because the problems I am interested in need them anyway.. August 25, 2011, 16:11 #5 Amdi New Member Join Date: Aug 2011 Posts: 4...
Likewise, the kinds of contrastive and overly explicit teaching methods employed by many instructors simplify the complexity of a daily language transaction or real-world experience too much. If language learning is to be internalized through any kind of implicit approach, the implicit nature of ...
