DAE Tools Project
Object-oriented equation-based modelling and optimisation software
DAE Tools is a cross-platform equation-based object-oriented modelling, simulation and optimisation software. It is not a modelling language nor a collection of numerical libraries but rather a higher level structure – an architectural design of interdependent software components providing an API for: - Model development/specification - Activities on developed models, such as simulation, optimisation, sensitivity analysis and parameter estimation - Processing of the results, such as plotting and exporting to various file formats - Report generation - Code generation, co-simulation and model exchange The following class of problems can be solved by DAE Tools: - Initial value problems of implicit form - Index-1 DAE systems - With lumped or distributed parameters - Steady-state or dynamic - Continuous with some elements of event-driven systems -

The FMI++ Library
A High-level Utility Package for FMI-based Software Development
The Functional Mock-up Interface (FMI) specification intentionally provides only the most essential and fundamental functionalities in the form of a C interface. On the one hand, this increases flexibility in use and portability to virtually any platform. On the other hand, such a low-level approach implies several prerequisites a simulation tool has to fulfill in order to be able to utilize such an FMI component. The FMI++ library addresses this problem for models and tools with... -

RElt
calculates overlap, kinetic integrals for numerical atomic orbitals.
The efficient algorithm calculating the overlap and the kinetic integrals for the numerical atomic orbitals is implemented. The described algorithm exploits the properties of the prolate spheroidal coordinates. The overlap and the kinetic integrals in R^3 are reduced to the integrals over the rectangular domain in R^2, what substantially reduces the complexity of the problem. We prove that the integrand over the rectangular domain is continuous and does not have any slope singularities. ... -

RAtom solves nonlinear Kohn-Sham equation for the neutral atom. The adaptive algorithm based on finite element method (FEM) is implemented. Discretization of the differential eigenvalue problem is done by finite element method with Lobatto polynomials as a basis functions. High order Gauss quadratures are applied in order to obtain the total energy of atom with absolut accuracy of 1E-6 hartree. Disctretization leads to generalized eigenvalue problem, which is solved by procedures from... -

Depolarization analysis tools
Tools for the accurate analysis of Raman depolarization measurement
This programme addresses the notoriously difficult problem to quantitatively link measured Raman depolarization values to theoretical polarizability tensor quantities, since quantum calculations do not incorporate experimental parameters. A numerical model is programme to calculate, for realistic experimental configurations, effective Raman line strength functions, which find their way into depolarization ratios. The model is based on interlinked integrations over the angles in the light collection path, and a finite Raman source volume along the excitation laser beam. The model deals as well with the conditional aperture parameters, associated with more than one optical component in the light collection path. ... -
