The S function returns a value between 0.0 and 1.0 along the neutral axis of a FE_PART. Function S corresponds to a non dimensional arc length.
This function is exclusively used in the definition of distributed loads. This function has an undetermined value if used in another context.
When evaluating distributed loads during a simulation, Adams Solver C++ sets the value of S at every integration point and computes the value of the expressions for the load and its derivatives. For example, an expression such as "DX(7)*S" will get a value depending on the specific location along the axis of the beam. The value of S is set by Adams Solver when evaluating the expression.
This function does not have arguments.
