 triangular network
 The algorithm is a combination of the method for unwinding fullerenes into a triangular network and the topological-invariants method for describing quasi-two-dimensional closed clusters. Five rigidly connected hard spheres form rod-like inclusions that can leap between sites of the triangular network. The generation of receptors in the animal cell's membrane was simulated by a model consisting of units in four possible states within a hexagonal area (playboard) ofn units of a triangular network. The original procedure using a regular grid is extended to surface representations based on an irregular triangular network (TIN). The simulation plane consists of a triangular network of points interacting with each other through both linear central force springs and bond angle springs, incorporating an appropriate element of a noncentral force contribution. 更多

 Figure 3 shows on time performance for the entire Delta network for the status quo and proposed scenarios.
 triangular networks
 (111) substrates give triangular networks of 60° dislocations lying parallel to ?110? directions resulting from motion on 6 slip systems. Three types of networks are considered: Delaunay networks with random geometry and random spring constants, modified Delaunay networks with random geometry and random spring constants, and regular triangular networks with random spring constants. Two-phase Delaunay and regular triangular networks, with randomness per vertex, provide generic models of granular media consisting of two types of grains - soft and stiff.

An operator-splitting algorithm for the two-dimensional convectiondispersion-reaction equation is developed.The flow domain is discretized into triangular elements which are fixed in time.The governing equation is splitted into three successive initial value problems: a pure convection problem, a pure dispersion problem and a pure reaction problem.For the pure convection problem, solutions are found by the method of characteristics.The solution algorithm involves tracing the characteristic lines backwards in time from a vertex of an element to an interior point.A cubic polynomial is used to interpolate the concentration and its derivatives on an element.For the pure dispersion problem, an explicit finiteelement algorithm is employed.Analytical solutions are obtained for the pure reaction problem.The treatment of boundary conditions is also discussed.Several numerical examples are presented.Numerical results agree well with analytical solutions.Because the cubic polynomial is used in the interpolation, very little numerical damping and oscillation is introduced even for the pure convection problem. 本文通过剖开算子法,把二维输运问题的控制方程剖分为三个子初值问题(纯对流、纯扩散及纯反应问题)。在任意三角形网络离散条件下,分别采用了特征线法解对流问题、显式有限元法解扩散问题及解析法解反应问题。文中重点探讨了纯对流问题的解法,利用特征线法将求解高时位对流浓度问题,转化为单元内部特征线上某点的低时位浓度插值问题。依据单元三结点的浓度及其导数,给出一种三次插值模式,从而能有效地减少数值阻尼,提高数值模拟精度。算例表明,本文数值模拟结果与精确的理论解吻合较好。 << 更多相关文摘
