Irregular triangular finite element adaptive grid-design method and its applications

The method of direct construction of irregular finite element adaptive grids is suggested. It is alternative with reference to method based on variation principle. The adaptive grid generation algorithm which uses controling function being found from boundary problem solution on a initial (rough) grid is described. The possibilities of essential increasing of accuracy and calculation process effectiveness are demonstrated on the concrete example of test and practical problem solution by means of system of finite element modeling and analysis (SFEMA).
