Taking advantages of the best features of flow-condition-based interpolation and split scheme,this paper proposes a flow-condition-based interpolation split scheme(FCBIS).A two dimensional triangle fluid element is built and a corresponding program is developed.The solution procedure is discussed and the numerical example solution is given to illustrate the efficiency and accuracy of the procedure.
