| Abstract: | In this article, introduces the definition of the transient temperature analysis and the features of the marching integration techniques, and investigates the stability and oscillation of numerical finite element solution of transient conduction temperature field with two-point time deference scheme. The features of several difference schemes have also been compared and analyzed. Through calculated examples, we test the validation of these several difference schemes, conclude and illuminate these several difference arithmetics in practical application. |
