The SD function returns the value of a global position or angle at a given location S along a beam. The value of S ranges between 0.0 and 1.0. A given value of S determines a unique location along the axis of FE_PART.
When evaluating the loads during a simulation, Adams Solver C++ sets the value of S at every integration point and computes the value of the distributed load and its derivatives. Accordingly, it sets the value of the function SD depending on the specified component.
Format
SD(comp)
Arguments
comp | An integer value specifying the kinematic component at a given position. All values are in the global frame. 1 = x component of position 2 = y component of position 3 = z component of position 4 = Psi Euler angle 5 = Theta Euler angle 6 = Phi Euler angle |
Example
FE_LOAD/1, FE_PART=3, FX=3.3*(SD(3)-DZ(7))
In this example, the distributed load depends on the global z position along the beam.
