I am doing a study where solar radiation has become the primary variable.  I would like to run a parametric "What If Analysis" and input various dates, times, and latitudes.  This solar radiation info is input as part of the general settings for the analysis and I have run individual scenarios (one at a time) with no problem.  They are steady state problems.   I would like to be able to run many scenarios at once.  This seems fairly basic but I haven't figured out how to do it. 

When I go to set up a parametric analysis and add a simulation parameter under the general settings there are no radiation or solar radiation settings listed.  Is it possible to do what I want or am I stuck doing each data point one at a time?

I am using SW 2015.

Thanks,
