Hi everyone, i am a new member in this forum. I am working on my PhD thesis and i have selected Ladybug tools as a tool in my method, and i will conduct a simulation process related to outdoor thermal comfort and i have to do thousands of scenarios (more than 100k) so my question is about if there any method or trick that can help to speed up the process
@Jadu for your application you might want to look into the pollination cloud and add-on toolset
With the pollination cloud you can run a whole batch of files at the same time.
@mostapha is the person who can actually explain the capabilities
Also look into colibri for generating lots of files with all stated available option combination i.e constructions and geometry combinations and such

Thank you, @TrevorFedyna! This used to be the case but most recently we stopped offering Pollination cloud simulation as a service.
Yes, cloud computing is not longer a service that we offer.
I recommend investing in a good desktop with an intel i9 CPU (with at least 20 processors). This is currently the best setup that I have found for running comfort mapping simulations efficiently.
Also, FYI. At the moment, we do not use the GPU in comfort mapping simulation, So an expensive GPU won’t be all that helpful for you here.
Since you are talking of around 100K scenarios, running everything on Grasshopper the standard way is probably not going to work out. You might want to spend some time figuring out how Honeybee and Ladybug pass input data to simulation engines like OpenStudio and Radiance and then import results back to Grasshopper.
It is usually more efficient to write out the simulation inputs in batches and then run them without the computational overhead of Grasshopper. With thousands of scenarios you are also likely looking at doing statistical analysis and summarization, something which is again better suited for a non-Grasshopper environment.
Stating the above from personal experience, however, I am aware that there are some people who have done thousands of simulations at scale by sticking to Grasshopper.
Have done huge batches in grasshopper, I found creating a number of VM’s and having each an E+ install and each running a batch to be pretty effective, but Im sure there is a more effective way
