Ask HN: I have an analytical solution for 3D Navier-Stokes, how to verify?

Analytical solution for a 3D velocity field under an impulsive external force using Dirichlet
sine series. The solution explicitly shows the acceleration (”explosion”) due to the force and
the exponential decay afterwards. This provides a reproducible model suitable for educa
tional or computational demonstrations.
