The Field Stress initial calculation type allows directly specifying in situ stress conditions on a volume of soil. It is now possible to assign a different field stress property to individual soil volumes and borehole layers, allowing you to independently input the initial stress state by magnitude and orientation for each of those clusters. The cluster-based field stress complements the global field stress and makes it easier to define the in-situ stress for geological models. This allows easily modelling non-uniform deepground conditions, such as those encountered in deep tunneling or reservoir geomechanics.
