Field Stress Vector
The load applied will be equal in magnitude and opposite in direction to the field stress on the boundary.
Note: this is a legacy load function from RS2 9.0. It is recommended that RS2 2019 users switch from using Field Stress Vector Loads to using Induced Stress Loads.
See the Tunnel Lining Design tutorial for an example of how to implement the use of an Induced Stress Load (Note: previous versions of this tutorial used a Field Stress Vector Load- the tutorial has been altered to reflect the recommended Induced Stress Load function in RS2 2019).
