Abstract :
In this paper, 2-point block method with two off-step points based on Backward Differentiation Formula (BDF) for solving stiff ODEs is formulated. The strategy of the developed method is to calculate two solution values of the method with two off-step points simultaneously at each iteration. Stability region and convergence of the method are also generated. The numerical results obtained are compared with the fifth order 2-point block BDF method to compare the enhancement of the method in terms of accuracy.
