I'm trying to see the results like the picture I attached(maybe to find the best option)

Acutally, I trying to make calibrationa and optimization.

Calibration through jEPlus and optimization throgh GenOpt.

How can I make a graph like below picture?

PMV is just an example!!

My parameter is

  1. infiltration rate [0.1: 0.01: 0.6]

  2. setpoint temperature [18: 0.1:32]

How can i make a graph from lots of data??

I did LHS(Latin hypercube sampling) 1000 times!

Am I have to choose AllCombinedResults??

Hi Jane, You can use jEPlus+EA for optimisation. It creates chart you want (so-called Pareto front). Nevertheless, it seems all your simulations finished with fatal error and didn't generate any outputs. Summary results should be in SimResults and AllCombinedResults files (you need to define in rvi or rvx file which outputs you would like to extract; outputs have to be specified in idf file as well). Having summary outputs in SimResults file you can use Excel to make charts. Pareto front and non-optimal solutions (as in your chart) can be created with scatter plot.

How can i make rvi file??

I read input output reference

and they said i have to use readvarseso but i cannot run the readvarseso. I also attached the picture! Thank you so much!!

@jane91: Please have a look at This Thread, this will show how you can create a .rvi file. You can also look at the example folder of JEPlus to get an idea.

Thanks a lot I did not fully undertand how to make rvi file... It is kind of tricky at the beggining, but I'm gonna study hard! :P
