ABSTRACT
Modelling must be auditable. The steps taken along the way and the assumptions and simplifications must be declared so that your findings-whether experimental or numerical-can be reproduced.
Modelling should be adequately complex. I suspect that the more complex the model the more the modelling itself will obscure the underpinning mechanics of soil behaviour and geotechnical system behaviour which we are trying to probe and understand. The art of successful modelling is to include just enough detail for the implied simplification to be reasonable for the particular application. Modelling assumptions will differ in different contexts.
