Abstract: Commonly, for being done a numerical modeling of any natural phenomenon, like as water flow pattern, need to an exquisite and modify calculated mesh. For gaining this standard calculated mesh, different calculated meshes must be analyzed sensitively. Thus, the optimum calculated mesh could be selected. At the present paper, the first, a powerful two dimensional numerical model which i...

In this paper we discuss the stability of a uniform Fréedericksz configuration in highly anisotropic thin nematic films. We show that the Fréedericksz transition in a bend geometry is at least two-dimensional, and it occurs at field strengths lower than the known classical threshold.

In this study, the CCHE2D model is used to analyse flow pattern in a meander reach of Gomati River. The finite volume method by numerical solve depth-averaged two-dimensional equations with

River meandering and anabranching have become major problems in many large rivers that carry significant amounts of sediment worldwide. The morphodynamics these are complex due to the temporal variation flows. However, availability remote sensing data geographic information systems (GISs) provides opportunity analyze morphological changes river both quantitatively qualitatively. present study i...
