The underlying models are typically parametric, nonlinear, hyperbolic partial differential equation systems, and hence, challenging for modelling, solving, and particularly model reduction. "morgen" is a modular, configurable, extensible, and open-source software platform, compatible with MATLAB and OCTAVE, designed for prototyping, testing, comparing, benchmarking, and uncertainty quantification of gas network models (discretizations), solvers (time steppers), and reductors (model reduction algorithms).
