In this paper, we deal with the method of grid generation. From the perspective of deformation mechanics, we propose a new method to generate grid with boundary constrain. Based on the stress balance equation on the node of the domain, the coordinate of the balance particle can be easily obtained by a very simple iteration method. Moreover, some discussions(More)
This paper deals with the generation of controllable density grid with boundary constrains. Based on improving the distribution of function value, a class exponential function is used to provide a method to generate grid by the curves of two parameter directions. Then, the optimal parameters are obtained by solving a constrained bi-quadratic programming.(More)
