Response Defination

Recommended Posts

hello Group


 


I need to define response from my solver output file (*.h3d) as X axis(frequency) vs Y axis (FRF).. how do i do it in expression builder..


 


please provide steps for doing it.


 


I tried using freq, frfmag etc from functions tab. was not able to get it. as it expects a vector i dont know how should i refer my frequency and frf response vector values here


 


Regards


Pratik

Hello,


 


When defining resppnses to track during an approach, HyperStudy works with scalar values not vectors.  So, for example, if you are going to run an optimization, the objective or the constraints but be scalar.


 


However, when using functions, you sometimes need to pass vectors as arguments to the functions.  These vectors are either (1) from the file source tab in the expression builder, (2) from the ASCII extracacts Tab in the expression builder, or (3) other responses.  When you create any of these three, they have an associated varname which is the variables assigned to them (by default it may be v_1 for example.  Simply pass the name as an argument to the function.


 


So for example, let's say you created vectors v_1 and v_2 which are the x and y data, respectively, on the curves mentioned above.  I could pick off the maximum using an expression max(v_2).
