Has this problem been resolved? I've come across the same problem in 5.1, where my second study uses the results of my first study as the value for the dependent variable not solved for. My first study is a stationary parametric sweep that calculates the electric fields for given values of potential differences between parts of the geometry, and the second study is a time dependent study that computes the trajectories of particles in the fields from study 1. Even if the parameter value to be used in the "Values of variables not solved for" section is set to "all", only the last parameter value is accessible in the particle trajectory plot. Does anyone have a solution to this?

Hi Alexander, did you figure this out? I'm using 5.0 and have the same annoying problem

Hi Arjun,
I did not ever figure this out. I end up manually creating each model file with the attributes that the sweeps would have covered, but this was mostly due to my workstation not being able to handle the memory required for even one of the sweeps. Instead of doing a file for each combination of parameters, you could just do one file for each parameter value in the first study, and then doing the parametric sweep as normal in the second study. You may also be able to combine both steps into one study and doing a parametric sweep over two parameters in that one study.
Good luck

Yeah, I have way too many parameters to do it individually. I'm running it on a cluster.
Anyway, thanks for your time.
Cheers.

I believe it works to use either the "Interpolated" or "Manual" settings for parameter value in the Values of Dependent Variables section. If it's the Interpolated setting, then the expected input is the value of the parameter from the previous study. If you are iterating over the same parameter in your study 2 parametric sweep, then put that parameter name in here. Alternately, with the Manual setting, you need to run over the whole numbers that index your previous parameter study (1, 2, 3, ... ).
