Finite-time free-surface approach of a point stresslet ($h^3=h_0^3-3St/(32\pi \mu )$)

A positive-strength parallel point stresslet below a flat shear-free impermeable plane is attracted by its identical reflected image. Its height satisfies $\dot{h}=-S/(32\pi \mu h^2)$ and formally reaches zero in finite time. Negative strength reverses the drift. Finite-body near-contact physics lies outside this singularity prediction.
