Study on Setting the Initial Nodal Temperature on the Joint Face of Concrete Dam

Because of lacking a rigid method of setting the initial nodal temperature on the joint face, the accuracy of temperature simulation would be affected in concrete dam. Based on finite element method (FEM) and principle of thermal conversation, we validate and extend a new method of setting the initial nodal temperature on the joint face in this paper. The result of temperature field simulation shows that this method has good accuracy in three-dimension temperature field simulation.
