Water Tube System DAE Work-Precision Diagrams

This is a benchmark of the Water Tube System, an index-2 DAE of dimension 49 from the IVP Test Set (Fekete 2006, water.F).

The system models water flow through a pipe network with 13 nodes and 18 pipes, accounting for turbulence and wall roughness. The network has two buffer nodes (nodes 5 and 8), external inflow at nodes 1 and 13, and external outflow at node 10. The external flows model a 17-hour demand cycle typical of municipal water systems.

Variables (49 state variables):

  • 18 pipe flows: φᵢⱼ(t), volumetric flow rates [m³/s]
  • 18 resistance coefficients: λᵢⱼ(t), Darcy friction factors (dimensionless)
  • 13 node pressures: pₙ(t) [Pa]

Physical challenges:

  1. Regime switching: Each pipe transitions between laminar (R ≤ 2300) and turbulent flow, with the turbulent Colebrook equation being implicit in λ.
  2. Scale separation: Flows ∼ 10⁻³, friction factors ∼ 10⁻², pressures ∼ 10⁵ — nine orders of magnitude difference.
  3. Index-2 structure: Variables 1–38 are index-1, while the 11 non-buffer node pressures (variables 39–49) are index-2 algebraic constraints.

We benchmark three formulations:

  1. Mass-Matrix ODE Form:M·du/dt = f(u, t) with diagonal singular M, solved with Rosenbrock-W methods and BDF.
  2. DAE Residual Form:F(du, u, t) = M·du − f(u, t) = 0, solved with IDA.
  3. MTK Index-Reduced Form: Defined symbolically with structural_simplify reducing from 49 to 32 states via automatic index reduction.

Network Topology

The pipe network connects 13 nodes via 18 directed pipes. Nodes 5 and 8 are buffer nodes (modeled with compliance/capacitance). External inflows enter at nodes 1 and 13; external outflow exits at node 10.

# 18 pipes: (from_node, to_node) — matches Fortran phi(i,j) ordering
const PIPES = [
    (1,2),  (2,3),  (2,6),  (3,4),  (3,5),  (4,5),

    (9,8),  (11,9), (11,12),(12,7), (12,8), (13,11)
]
const NNODES = 13
const NPIPES = 18

# Pressure variable mapping: node → y-index (Fortran ordering)

RHS Function

The right-hand side has three blocks:

  1. Momentum equations (1–18): Darcy-Weisbach pressure drop for each pipe
  2. Colebrook equations (19–36): Implicit friction factor relationship
  3. Node balance (37–49): Kirchhoff mass conservation at each node

The Colebrook equation for turbulent flow is: $\frac{1}{\sqrt{\lambda}} = 1.74 - 2\log_{10}\left(\frac{2k}{d} + \frac{18.7}{|R|\sqrt{\lambda}}\right)$

where $R = |u_{ij}| d / \nu$ is the Reynolds number. In the laminar regime ($R \le R_\text{crit}$), the Colebrook equation uses $R_\text{crit}$ in place of $R$, and the momentum equation uses the Hagen-Poiseuille law instead.

All flows start at zero, friction factors at the laminar Colebrook value λ₀ ≈ 0.04752, and all pressures at 109800 Pa. This is a consistent initial condition (the RHS evaluates to zero at t = 0).

Mass-Matrix ODE Form

The mass matrix is diagonal with three blocks:

  • M[1:18] = ρL/A (flow momentum — differential)
  • M[19:36] = 0 (Colebrook equations — algebraic)
  • M[37:38] = b/(ρg) (buffer node balance — differential)

MTK Index-Reduced Formulation

ModelingToolkit can automatically reduce the index-2 DAE. We define the full system symbolically — 18 flow momentum equations, 18 Colebrook algebraic equations, 2 buffer node balances (differential), and 11 non-buffer node balances (algebraic) — and let structural_simplify eliminate the index-2 constraints.

The regime switching (laminar/turbulent) is handled with ifelse, which ModelingToolkit propagates through the symbolic graph.

Info Packages marked with ⌃ and ⌅ have new versions available. Those with ⌃ may be upgradable, but those with ⌅ are restricted by compatibility constraints from upgrading. To see why use `status --outdated -m`
