No Monte Carlo simulations #21

Closed dwimjpurnomo closed 1 year ago

dwimjpurnomo commented 1 year ago

I tried to disable the perturbation by making the lower and upper bound to be equal. But when I try to do repetitions, the outputs are still different. How to make the outputs to be equal when we repeat simulations? Attached is the input decks and the outputs that I get. https://drive.google.com/file/d/1n7ORrwuOdYdwQhtmF1Qq6HTUsa_Jfsuk/view?usp=sharing

Even without perturbations on the inputs you will still see different outputs due to the stochastic nature of spotting. What happens if you disable spotting?

lautenberger commented 1 year ago

@dwimjpurnomo I confirmed that with your input deck the outputs are the same for each ensemble member provided spotting is disabled and WIND_FLUCTUATIONS = .FALSE.. Enabling spotting or wind fluctuations is going to cause differences across ensemble members. Closing this issue.
