Sensitivity Analysis of Initial Value Problems with Mixed Ode's and Algebraic Equations.
Abstract
An efficient method is described for sensitivity analysis of nonlinear initial value problems, which may include algebraic equations as well as ordinary differential equations. The linearity of the sensitivity equations is utilized to solve them directly via the local Jacobian of the state equations. The method is implemented with the implicit integrator DASSL and is demonstrated on a stiff industrial reaction model. Keywords: Numerical integration, Stiff equations, Parametric sensitivities, Initial value problems, Newtons method, Chemical kinetics.
