ULS sensor

The ULS sensor can be added by clicking the sensor button in a  Support structure  part as shown in the figure below 

The ULS sensor  provides the followin fields:

Field	Unit	Description
Max. normal stress	MPa	At any given point in time, the maximum value of normal stress for all the elements composing the support structure. Normal stress is computed according to the equations described in the  Stresses and responses  document
Max. normal stress (perc.)	%	Maximum normal stress as a percentage of the yield stress for steel, currently set at 355 MPa.
