Explicit and implicit methods are approaches used in numerical analysis for obtaining numerical solutions of time-dependent ordinary and partial differential equations, as is required in computer simulations of physical processes. Explicit methods calculate the state of a system at a later time from the...
做有限元(Finite Element Model, FEM)分析的时候很容易面临选择显式或隐式求解器的问题。例如,ABAQUS的Standard 求解器指的是隐式求解,而 ABAQUS/Explicit 显而易见指的是显式求解;在ANSYS中,Mechanical APDL默认的是隐式求解,而ANSYS Mechanical/Explicit Dynamics 主打的是显式求解;此外,ANSYS 中还包括了另外收购...

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 with only simple calculations performed at each timestep while implicit schemes are more difficult and can involve many iterations per timestep. Explicit sc...
The dening distinction between implicit acquisition and explicit learning of L2 was that of Krashen (1982). He argued that adult L2 students of grammar-translation methods, who can tell more about a language than a native speaker, yet whose technical knowledge of grammar leaves them totally in ...

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 ...
The Cognitive Psychology of Implicit and Explicit Learning ; Explicit learning: a more explicit process whereby various mnemonics〔记忆术〕, heuristics 〔启发方式〕and strategies are engaged to induce a representational system. Focus on methods in learning process. ; Dekeyser Implicit learning: learning...
We analyze the discretization of nonlinear parabolic equations in Hilbert spaces by both implicit and implicit-explicit multistep methods and establish local stability under best possible and best possible linear stability conditions, respectively. Our approach is based on suitable quantifications of the ...
