We have collected a number of demonstration examples that can serve as the starting point for your own scripts. They can be found in the DEMOS directory in your installation folder. Its sub-directories serve the following purposes.
models/ Contains the actual benchmark model data or functions for their generation
FDM/ Rail/ Both demonstrate the use of the “default” operators, i.e., the default set of user supplied functions (usfs). While Rail/ contains a symmetric system for a FEM semi-discretized heat equation, FDM uses a finite difference semi-discretized heat equation with convection and is thus non-symmetric.
DAE2/ Demonstrates the use of index-2 Stokes-type DAE systems. By default a scalable finite Volume discretization for a Stokes system is used. There is also an option to use the FEM model for a Karman vortex shedding in a 2d domain. This, however, requires an additional download of approx. 270MB per Reynolds number.
TripleChain/ Uses the Truhar/Veselic model with three coupled mass-spring-damper-chains to demonstrate the use of the structure exploiting second order usfs. The directory contains both the case for the “so_1” usfs and the “default” set to demonstrate the advantage of the first.
DAE2_SO/ DAE3_SO/ Show the use of the “dae_2_so” and “dae_3_so” usfs for second order index-2 and index-3 systems, mechanical systems with algebraic constraints on positions or velocities serve as examples here.
RI/ Demonstrates the solver for Riccati equations with indefinite quadratic terms.
Bilinear/ Features the bilinear variant of the Rail model and related Matrix equations.
