Study And Application Of Flow Visualization Of The 2D Mathematical Model

In hydraulic engineering,mathematical model of the application of an extremely important value,but the expression of the mathematical model has also not intuitive, data-processing complex,such as disadvantage,which significantly restricted the extent of the development of mathematical models,how to open,friendly interface,vivid demonstration of the effect of displaying the results of numerical simulation model will be calculated on an important research direction.Visualization in scientific computing technology can be a good solution to this defect.Therefore,this combination of visualization in scientific computing technology on the mathematical model of postprocessing carried out related research,mainly following results were achieved:(1) in the study two-dimensional mathematical model of flow visualization on the basis of the developed mathematical model of two-dimensional flow visualization system.Realize the orthogonal curvilinear grid auto-generated,drawing,reading terrain features such as data,graphics rendering module to solve the flow field,flow lines, contour lines,such as the production of dynamic visualization and display.(2) use of Surfer,tecplot,Autocad secondary development to resolve the flow field, isogram Rendering ineffective defects.(3) the use of mixed programming technology and secondary development of technological breakthroughs in different programming languages and different application software interface between the communication and problem.(4) the use of visualization technology to Office Excel for the secondary development of innovative solutions of practical engineering,such as artificial terrain data read errors that may arise,and be able to revised data into the mathematical model for calculating the required data format.(5) the use of VB programming techniques,give a Windows-style menus,toolbars and window operation,friendly interface and a high degree of visualization.
