A Class of Moving Boundary Problems Arising in Industrysible in several of the problems, the failure of the smoothing transformations suggests that such time-reversed problems may be ill-posed. Corroboration of this conjecture might be provided by a formal linear stability analysis but this requires an approach different from the usual stability analysis of moving boundaries with codimension unity.

Formal Science from Logic to Mathematics,Method (FPM) approximating the solution by finite sets of particles in a rigorously defined way. Convergence results are cited while practical aspects of the algorithm are emphasized. Ideas for the transition to the Navier Stokes domain are shortly discussed.
