The DEMOS/models/ directory contains the collection of benchmark systems used in the demonstration examples.

Data_Rail The well known Rail aka Steel Profile example from the Oberwolfach Collection and a bilinear reformulation on the same geometry.

FDM_2D Contains the functions for generating scalable models of the finite difference semi-discretized model of a heat equation on the unit square. The functions support convection, as well as reaction terms at the users choice. They are exact copies of the files from the LyaPack package.

NSE Prepared to store the external download for the Karman vortex shedding model in a 2d channel.

SingleChainMSD A simple scalable mass spring damper system

TripleCchain The Truhar/Veselic model made from three coupled mass-spring-damper chains. Size, i.e. masses per chain, and damper viscosity, as well as parameters in the Rayleigh damping used here can be set by the user. An interesting parametrization can be found in example_from_Saak09.m

msd_ind3_by_t_stykel Tatjana Stykel’s mass spring damper system with holonomic constraints, i.e., the index-3 DAE case.

stokes The finite volume semidiscretized Stokes (index-2) model by Tatjana Stykel and Michael Schmidt.

The M.E.S.S. team would like to thank Tatjana Stykel for providing the routines for the index-3 MSD model and the stokes model.
