Characteristics computational scheme of numerical wave model under complex topography conditions 復雜地形下海浪數值模式的特征線計算格式
We will describe ongoing work , suggested by the computational schemes described earlier , which shows that several visual tasks can be learned from a set of associations 我們將透過先前的統計資料,探討正在進行中的研究許多視覺認知是運用聯想而學習的。
Using the approximation form of lumped mass matrix instead of the mass matrix in finite element discretization in space , backward differencing scheme in time , an implicit computational scheme is yielded , it proved the convergence estimate for this implicit scheme 對有限元離散中引起較大誤差的質量矩陣,采用了近似形式的集總質量矩陣來代替,時間項采用向后差分,得到了一個隱式的計算格式,證明了計算格式的收斂性及其收斂速度估計。
The purpose of this dissertation is to study the lagrangian method and conservative rezonning algorithm . finite volume scheme is used for lagrangian equations of hydrodynamics . because of the pressure gradients " influence upon velocities and energy , computational scheme is proposed for momentum equation on two control volumes in order to suspend the time when the mesh becomes distorted 本文的目的是研究lagrange方法及重映算法,主要內容可分為以下幾個方面:首先從積分形式的二維lagrange流體力學方程組出發,用有限體積格式進行計算,考慮壓力梯度分布對速度和能量改變的影響,構造了在兩個控制體上的動量方程的計算格式,使得速度的改變受其周圍八個壓力的影響,在一定程度上推遲了網格相交的進程。
