Geoengineering computer simulation looks pretty but is it the real world?

Abstract

Correct formulation of the differential equation system for equilibrium conditions of subsoil, especially of controlled numerical calculation view-point, is discussed. A question of solution stability is also discussed. The solution of problems, which are ill-posed, have no practical value in the majority of cases and in this way the engineering prognosis can lead to the real disaster. The object of this paper is quite relevant from the application point of view. Numerical calculations of boundary value problems must often be performed as true predictions. Unfortunately, the ability to submit a reliable prediction seems to be lacking in geotechnical engineering. Several reasons, which may be responsible for this disappointing state are described.
