Rational setup of the initial and boundary conditions is indispensable for numerical analyses of various geotechnical problems particularly when the sophisticated method such as finite element analysis is applied. In the present paper, contribution of various geometrical parameters of the finite element mesh as well as the modeling of the loading and time step to the calculated performance is discussed with a series of sensitivity analyses. The elasto-viscoplastic finite element code is used to calculate the stress and deformation of the clay foundations due to embankment load. The difference in calculated settlement, lateral displacement and excess pore water pressure amounts to 10 to 20% with the different setup of the above-mentioned parameters.
