从方程的能量结构导出解的各种性质的能量法是偏微分方程的经典方法之一。当数值格式也具有能量结构时,同样可以将能量法应用于该格式。在本文中,我们通过证明解的存在性和误差估计来介绍能量法在保结构有限差分格式中的应用。
The energy method to derive various properties of the solution from its energy-structure of the equations is one of the classical methods for partial differential equations. When the numerical scheme also possesses the energy-structure, the energy method can be applied to the scheme in the same way. In this article we introduce an application of energy method for the structure-preserving finite difference schemes through proofs of the existence of the solution and error estimate.
