Hi, I wonder if for parametric EnergyPlus runs (for example with Colibri) or multiple EnergyPlus runs based on optimization algorithms (with components that I am not aware of for the time being), we can use the full capacity of local processor in parallel simulations. Best, Farhang

If you want to use the plugins as it is then the answer is no, and it’s because how Colibri, Galapagos and all the other iterative plugins in Grasshopper work. Whenever you change a value in Grasshopper it starts a Solution and once the solution is Expired and Grasshopper starts a new Solution ther…

@farhang.tahmasebi the answer is true. You can try this example. http://hydrashare.github.io/hydra/viewer?owner=chriswmackey&fork=hydra_2&id=Parametric_Energy_Model_With_Colibri

@minggangyin I meant simultaneous runs using multiple processor cores. As I ran that example file, EnergyPlus models were running one by one.

Hi @mostapha , thank you for this suggestion, I’ve been having a problem when I follow these steps with Electric lighting energy, ElectricEquipement energy, Natural Ventilation energy and total peoples gain which becomes 0 in this method,( this values are not 0 when I do the parametric study in the…

Hi @mostapha How can I write all the design options? Manually?

@farhang.tahmasebi this is probably a dull comment, but could you look at writing idf files using the colibri structure, then execute them using something like JEPlus or JESS, the read the results and feed back into colibri to format the data into something like design explorer?
