In the proposed UFT the already first, most granular extended H(1/2)-energy Hilbert space of the standard variational mechanical H(1)-energy Hilbert space enables a well-posed 3D non-linear, non-stationary Navier-Stokes problem (existence and smoothness by a bounded H(1/2)-energy norm estimate); this solves the related problem of the Clay Mathematics Institute, Cambridge.
