There are two acceptable options: 1. The parameters are updated along with the strains during the analyses. 2.

Hence, it would required you to write your own constitutive soil model.</p> <p>Option 2) is not possible. Well, first of all because soil parameters are not determined in nodes but in stress points - but apart from that, it is not possible to change parameters in individual stress points.</p> <p>With kind regards,</p> <p>Dennis Waterman</p><div style="clear:both;"></div>
