Parametric performance inconsistency #84

Closed qualand closed 2 years ago

qualand commented 2 years ago

Parametrics analysis appears to not account for multiple heliostat templates used in field layout.

To reproduce error:

  1. Import a field that consists of two different heliostat templates. (This requires setting up two heliostat templates. In the user example, they had two heliostats with different focal lengths.)
  2. Run "Performance Simulation"
  3. Save results
  4. Run "Parametrics" with using the same "fluxsim: Hour of the day" as the "Performance Simulation"
  5. Compare results

From the example the user provided, the biggest difference appears in the image intercept efficiency. Performance Simulation: 10.03 % Parametric: 8.68 %

It is expected that these two work flows would provide the same results.

The Parametric resulting image intercept can be reproduced by setting all heliostats to the first template. The heliostat template value must be being reset somewhere in the workflow.
