Evaluate Young’s modulus of a lattice structure and optimize it

  Hi,
  
  I'm trying to evaluate the young's modulus in the y direction of the lattice structure shown in figure. I set fixed support on the bottom surfaces and I applied a force on the top surfaces. I measured the stress and the strain probe to the top surfaces and I divided them in order to obtain the young's modulus of the entire structure. It returns a reasonable result, but I want to set this result as a parameter in order to optimize it. How can I do it? (I didn't make the division in Ansys, I don't know how can I do this kind of operation).
  
  I use static structural in Ansys 18.0.

  In Mechanical Solution, you can define the Stress and Strain as parameters by LMB click on small box next to their value. In Workbench you can see parameter set defined. Double click to open the parameter. In the output parameters you can defined third parameter by expression such as P1/P2.
