abstract = {The paper presents first a linear stability analysis for
the time-parallel Parareal method, using an IMEX Euler as
coarse and a Runge-Kutta-3 method as fine propagator,
confirming that dominant imaginary eigenvalues negatively
affect Parareal’s convergence. This suggests that when
Parareal is applied to the nonlinear Navier-Stokes
equations, problems for small viscosities could arise.
Numerical results for a driven cavity benchmark are
presented, confirming that Parareal’s convergence can
indeed deteriorate as viscosity decreases and the flow
becomes increasingly dominated by convection. The effect is
found to strongly depend on the spatial resolution.},
