| Abstract: | The formula and the implementation of the analytical sensitivity analysis are discussed based on the p element analysis. The implicit differential sensitivity analysis formula is derived for 2D geometric elements, and the strategies are given for selecting a start solution of the PCG iterative method used to solve the sensitivity equations. The computational results show that the method is high efficient and high accuracy. |
