Variable Step Block Hybrid Method for Stiff Chemical Kinetics Problems

open access: yesApplied Sciences, 2022
Integration of a larger stiff system of initial value problems emerging from chemical kinetics models requires a method that is both efficient and accurate, with a large absolute stability region. To determine the solutions of the stiff chemical kinetics

On the convergence of Lawson methods for semilinear stiff problems [PDF]

open access: yes, 2017
Since their introduction in 1967, Lawson methods have achieved constant interest in the time discretization of evolution equations. The methods were originally devised for the numerical solution of stiff differential equations. Meanwhile, they constitute

Stiff systems of ordinary differential equations. III. Partially stiff systems [PDF]

open access: yesThe Journal of the Australian Mathematical Society. Series B. Applied Mathematics, 1982
AbstractThe partially stiff system of ordinary differential equationsis studied by the methods developed in the earlier papers in this series. Here e is a small positive parameter, x and y are n- and m-vectors respectively, and A is nonsingular. A useful basis for the solution space of the homogeneous system is constructed and the method of variation ...
