Computing the sensitivity using the Sensitivities at the Physics node and Study node

Please login with a confirmed email address before reporting spam

Hello,

Please, find my attached mph file. rho0 is a variable. I needed the sensitivity of my objective integral (ps.Ws) with respect to a control variable (rho). I have defined the objective integral, integral (ps.Ws) and the control variable, rho in the Physics sensitivity module. I made the initial value of rho to be rho0. Having run the study, I tried to plot rho in the result menu of the study node. Instead of obtaining a distribution (similar to rho0), I am only getting a number. With this, I will not be able to extract the correct sensitivity of integral(ps.Ws) with respect to rho at the study node. Please, help me. rho should be a distribution, not a number. Thank you so much.
