Modeling Pneumatic Networks (3)

• Real-world model:
  • medium-sized model from industrial partner
    • implemented in PneuBib + MFL
    • 60 components (3 pumps, 1 tank, 12 consumers, 17 simple tee branches)
    • ≈ 4500 equations
  • porting to PneuBibTFS
    • specify flow directions
    • include tank via a small loop
    • initial pressure of tank = pump pressure (all equal)
    • ≈ 1750 equations
  • simulation stops after 1 s
    • several flows have wrong direction
    • due to identical pump pressures
  • remedy
    • increase pressure of one pump marginally
    • → all flow directions fixed
    • → model runs, reproduces results of MFL version qualitatively
