Abstract :
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. Numerical results show the effectiveness and advantage of the method.
