ABSTRACT
New developments in the field of geomechanics lead to mathematical models, which will then be implemented in computer codes. Hand in hand with the growing power of hardware and the increasing user-friendliness of office-software, geotechnical engineers will also put higher demands on the geotechnical software that they use. The still growing demand for the “outside”, i.e. easy-to-use computer codes, is evident. The code is reasonably easy-to-use, but it lacks depth when considering the constitutive modelling of soil behaviour. The present short-term planning leads to difficulties within the Plaxis group. Computer modelling requires both theoretically talented co-workers and staff members which are gifted in the field of information technology. The long-term stability of this company, however, requires long-term planning and some growth. In 1989 the growth was clear as one had to expand Plaxis from an embankment-code towards a general geo-code.
