I was then asked: "Plant component node for sensor?" and I assumed that because I have a one-node flat plate collector that the answer to this was 1. A followup question appeared: "2nd Plant component index for sensor?". What number/index are they asking for here? I tried to write the index number for the plants database for the tank but it does not seem to work. I also tried with the index of the tank in my plant network file (i.e. the number of the plant component there). </div> <div style="font-family:arial,sans-serif;font-size:13px">When i run the simulation and open results analysis, a warning appears:</div><div style="font-family:arial,sans-serif;font-size:13px">WARNING in filename.cfg: no chars found for plnt res string in: *splr</div> <div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">Does anyone know how to fix either of these two problems?
