t = 0.00 s | c(A₀) = — m/s | peak p = — mmHg
Full 1D Navier–Stokes (MUSCL + Rusanov, Heun RK2) on an elastic tube with Reymond–Laplace closure p(A) = pext + β(√A − √A₀).
Inlet: Gaussian flow pulse. Outlet: 3-element Windkessel or non-reflecting boundary. Pipe wall shown dilated proportionally to A(s,t);
colour = pressure; curve = Q(s,t).
