....based on the work of Lurmann et al. see [14] and Atkinson et al. see [1] is representative of those presently being used in the study of chemically perturbed environments. The results are tested against an exact solution (which was considered to be that obtained with the code RADAU5 [7] with very tight tolerances) In Figure 1 a work precision diagram is shown for QSSA, Extrapolated QSSA, and VODE (a BDF code, see [17] The number of significant digits is a measure of the error over all components. For the same computational effort Extrapolated QSSA is clearly more accurate ....

....direction of the flow of information, and it is therefore best suited for two point boundary value problems. Quite differently, for initial value problems it is sometimes desirable to have stiffly accurate schemes, that are able to damp the higher frequencies components from the computed response [11]. This is achieved in practice by forcing a lack of symmetry in the scheme, that incorporates the knowledge on the direction of flow of information within the element. It is possible to derivesuchschemes in the present framework, allowing one single jump discontinuityatx i while enforcing the ....

.... projection and pressure Poisson reformulations (e.g. 8, 12, 20, 24, 26] Another topic of great recent interest is the numerical solution of differentialalgebraic equations (DAEs) In their most popular special form, these are ordinary differential equations with some equality constraints (e.g. [6, 13]) Recall that an important concept for measuring the difficulty in solving DAEs is given by the (differential) index, which is defined by the minimal number of analytical constraint differentiations such that the DAE can be transformed by algebraic manipulations into an explicit first order ....

For RK methods whose coefficients satisfy 1 0 = j a for 1 = j. s , it is natural to take 1 : nn Zz . Other alternatives based on RK coefficients are half explicit RK methods [21 23], partitioned RK methods [24,25] and SPARK methods [26] The RK method used in our numerical experiments is the 2 stage Lobatto IIIA method, simply speaking the trapezoidal rule. Convergence of order 2 for the y component is achieved, meaning that the global error of the y component on a ....

Introduction In this article a broad class of systems of possibly stiff and implicit differential algebraic equations (DAEs) is considered, including Hessenberg DAEs of index 1, 2, and 3 [1,5,6,8,9]. These equations encompass the formulation of mechanical systems with mixed constraints of holonomic, nonholonomic, scleronomic, and rheonomic types [7,16,17] Solutions to these DAEs can be approximated numerically by applying a class of super partitioned additive Runge Kutta (SPARK) methods, ....

These equations encompass Hessenberg DAEs of index 1, 2, and 3 [1,5,6,8,9]. They also include the formulation of mechanical systems with mixed constraints of holonomic, nonholonomic, scleronomic, and rheonomic types [7,13,16,17] In mechanics the quantities q,v,p represent respectively gener alized coordinates, generalized velocities, and generalized momenta.

....high resolution on a wide variety of nonlinear circuits. It is also suitable for combining with matrix implicit Krylov subspace solvers in order to analyze large circuits with moderate computational cost. Another way of viewing our discretization scheme is as an implicit Runge Kutta (IRK) method [13]. Leveraging the theoretical framework available for analysis of IRK methods has given us an increased understanding of limitations of numerical techniques traditionally used in analog and RF circuit simulation, in particular the computational advantages associated with the superior stability ....
