Abstract: In this work, computational analysis of generalized Burger’s‐Fisher and generalized Burger’s‐Huxley equation is carried out using the sixth‐order compact finite difference method. This technique deals with the nonstandard discretization of the spatial derivatives and optimized time integration using the strong stability‐preserving Runge‐Kutta method. This scheme inculcates four stages and third‐order accuracy in the time domain. The stability analysis is discussed using eigenvalues of the coefficient matrix. Several examples are discussed for their approximate solution, and comparisons are made to show the efficiency and accuracy of CFDM6 with the results available in the literature. It is found that the present method is easy to implement with less computational effort and is highly accurate also.
