Introduction
Automation makes things easier...
... and it mitigates the human factor!

XIII Russian PLAXIS User Meeting | October, 20207
My vision is:
Make complex things easy by automation
PLAXIS examples from the past:
• Making FEM accessible to geotechnical engineering practice
➢ Automatic load and time-stepping
➢ Enhanced mesh refinement
➢ Advanced, yet robust soil constitutive models with clear model parameters
➢ Simulation of soil lab tests, calibration of model parameters
Vision

XIII Russian PLAXIS User Meeting | October, 20208
All this starts from scientific background, but with focus on practical application, hence
from Research to Application
Collaboration with universities, research centres and industry:
➢ Delft University of Technology
➢ University of Graz, Trondheim, Grenoble, Oxford, Athens, MIT, Berkeley, ...
➢ Institutes: Norwegian Geotechnical Institute (Norway), BAW (D), Deltares (NL)
Previous and current work on automated parameter determination:
➢ Publication on HSsmall model parameters based on Relative Density only
➢ Parameter Guide 1.0: Too complex; black box; not the right time
➢ Publication in : several positive responses
➢ Publication in
➢ Publication in (in Dutch)
➢ Presentation at ECSMGE in Rejkjavik: if WE don't do it (together with our academic partners), competition will do it (and it will grow beyond our control)
➢ MSc projects at TUDelft: 1st student graduated; 2nd half way; 3rd about to start
