Abstract: “In this contribution we present the LptNumerics library for processing of equation systems that are provided via the CAPE-OPEN ESO interfaces. The library provides functionality for the pre-processing of an equation system and its solution. Here the term pre-processing refers to the steps required prior to solving a model in an equation-oriented solution approach. The library is implemented in C++ and can be used within any equation-oriented application. This contribution discusses the design and implementation of the library and presents two application examples.”

Comments: the LptNumerics library provides functionality applicable in different equation-oriented modelling and simulation tools. The functionality builds upon  the CAPE-OPEN Equation Set Object which is at the core of the CAPE-OPEN Numerical Solvers interface specification.
