A framework for analysis of computational load of CAPE tools

This work presents a framework for analysis of computational load centred on three components: i) the model of the system (the model), ii) the model of the mathematical/engineering problem (the problem) and iii) the numerical solution method(s) used for solving the combined model/problem formulation (the solver(s)). The framework classifies computational load as emerging from four mayor elements: i) expression (function/residuals and Jacobian) evaluations encapsulated in the model, ii) solver calls, iii) foreign services external to the core modelling-and-solution engine, and iv) overheads. The framework is used to analyse the computational cost of two simulation case-studies.
