概要

• 論文の詳細を見る

• An inherent contradiction in the finite-difference methods for the Laplace equation is demonstrated. The grid size in a practical computation must, on the one hand, be fine enough to ensure the numerical accuracy, but, on the other hand, be necessarily large to avoid an ill-conditioned difference equation system. Higher-order schemes are shown to be advantageous in terms of both the accuracy and the condition of the difference equation system.
