✦ Synopsis

The computation of the vector potential distribution in rotationally-symmetric electron lenses can be made with the help og the finite element method. It handles effectively both the complicated geometry of the circuit and the magnetic saturation effects. The paper describes the calculation of the energy functional in one triangle, the mesh-layout method and the numerical methods used to solve the resulting set of linear equations.

## Abstract Traditionally, sedimentation and self‐weight consolidation have been viewed as physically distinct processes requiring separate treatment. Relatively recently, Pane and Schiffman^1^ and also Philip and Smiles^2^ have suggested that the two processes may be described by a single partial
