Abstract:

The mixed hyperbolic-elliptic Tricomi equation is solved approximately by first transforming the equation to a positive first order system and then discretizing the system by the finite element method. An experimental Oh sup 2 L sub 2-rate of convergence is obtained. The authors compare the results with results obtained for this problem by finite difference methods. Author
