Parametric Study (Urgent)

Hello,

I have a structure that I have simulated before, and it has bolts and welds so it's taking me around 5 minutes to compute. I am trying to find out at what load the maximum stress is 180 MPa (per example), is there a way (using load as a parameter or something) to do that using solidworks?

I wanted to find it by iterations but it'll take me too long, especially that I have plenty more loads to find out.

Thank you,
