ABSTRACT: Numerical analyses are routinely performed in geotechnical engineering to study the stability of slopes, to determine the pore-water pressure conditions in a domain, or to calculate the resulting stresses and strains following a perturbation. These three types of analysis are among the most reported analyses in geotechnical reports and yet, convergence information is seldom displayed with the results. Convergence is inherent to numerical processes; it dictates whether the results of an analysis can be trusted or not. Hence, geotechnical engineers should strive to diligently report the convergence status of any numerical analysis they perform. Convergence is discussed in this paper in the context of the three numerical analysis types aforementioned. Propositions to improve convergence disclosure are presented.
