Abstract:An object-oriented finite element analysis system SiPESC .THERMAL is developed for thermal problems based on software integration platform for engineering scientific computation (SiPESC) and engineering database . The plug-in and extension design patterns are used for the flexibility of the system which allows the analysis task to be assembled dynamically .This system has the features of generality ,openness and scalability .The Factory and Builder design patterns are used for the element computation module which is convenient to the expanding of the element library .The general heat elements used in practice have been implemented in the system . T he geometry face elements are defined for the flexible handling of various geometry faces and different face loads .The handler for heat flux and heat convection boundary on different boundary elements has been implemented .The system′s efficiency and ability for solving engineering problems are tested by several representative numerical examples .
