These Simulink blocks contain transfer functions that model the pressure and flow transients for axisymmetric 2D viscous flow of a compressible fluid in a straight rigid circular cross section pipelines. Three models are available: (1) pressures at the ends (2) flow rates at the ends (3) pressure at one end and flow rate at the other Filtering is incorporated to reduce numerical oscillation (Gibbs phenomenon). See J. Dyn. Systems, Meas. & Control vol 122 (2000) pp. 153-162.

% DYNMODES calculates ocean dynamic vertical modes % taking a column vector of Brunt-Vaisala values (Nsq) at % different pressures (p) and calculating some number of % dynamic modes (nmodes). % Note: The input pressures need not be uniformly spaced, % and the deepest pressure is assumed to be the bottom.
