Herein, we develop an adaptive implicit鈥揺xplicit method (A-IEM) to enhance the robustness and efficiency of computational failure models. Initially, implicit algorithms are applied for non-linear analysis, during which critical nodes that hinder the convergence rate are identified through a ...
Implicit-explicit methodNumerical approachSeveral Non-pharmaceutical Intervention for facing the epidemic spread, such as effects of mass vaccination, shortage of healthcare people (HCP) and a restriction of social movements (RSM) have aroused extensive attention, in addition that the medication or ...
y_{k+1}=\frac{-1+\sqrt{1+4 \Delta t y_{k}}}{2 \Delta t} 注意:大多数情况下,隐式方程的求解是很困难的,不像本例中这么简单地使用一个公式就可以解出y_{k+1}的值,这时候就需要使用各种寻根方法,比如牛顿方法(Newton's method)等。 小结:由于在计算 y_{k+1} 的过程中,我们不能简单地...
An analysis of this method was performed in [23], where it was shown that although embedded methods result in smaller linear systems, they are only conservative on the dual volumes [24]. Combining hybridization with standard formulations has been shown to provide significant benefits in reducing ...
But for slower dynamics, an implicit method is more stable. The industrial problems are governed by high frequency (impact, ) during short time intervals and slower dynamics (spring-back, ) during other time intervals. The optimal solution is then to have both implicit algorithm and explicit ...

Would you please tell me the definitions of implicit method and explicit method? And what are the differences for their usage? Last question is that what is the important factor for my decision of using either one? Thank you for your help! Donna ...

The stiff chemistry and all vertical transport processes (turbulent diffusion, advection, deposition) are integrated in an implicit and coupled manner by a higher order BDF method. High order accuracy and stability conditions are investigated for this class of implicit-explicit schemes. The numerical ...
