New third order Runge Kutta based on contraharmonic mean for stiff problems
ODE solver Runge-Kutta method contraharmonic mean
2009/12/30
In this paper we introduce an explicit one–step method that can be used for solving stiff problems. This method can be viewed as a modification of the explicit third order runge-kutta method using the...
Design of new diagonally implicit Runge朘utta methods for stiff problems
ODE solver Runge-Kutta method
2009/12/30
This paper presents new fifth-order diagonally implicit Runge-Kutta integration formulas for stiff initial value problems, designed to be Lstable method. The stability of the method is analyzed and nu...
