Abstract. In this paper, we show that a Simpson's type second derivative method (SSDM) can be adapted to cope with the integration of stiff systems in ordinary differential equations (ODEs). This is achieved by combining the SSDM with an additional method and implementing them as a block method. The block method is shown to be A-stable and of order 6. Numerical results produced by the block method show that the method is competitive with existing ones in the literature.
