How to set Gradients analysis in hypertudy？

How to set the sensitivity analysis result in hyperstudy?
My model is to consider the stiffness of three springs with three directions each, and find the sensitivity of the modal frequency to the spring stiffness.

Or there are references that I can't find.  

Click add all under Gradients and then evaulate to display the error shown below.

What expression should I enter to complete the gradient calculation?

Thanks a million.
