EDIT: I just noticed you’d already asked about Dragonfly specifically here so you’ve already been introduced to Dragonfly and UWG. My bad sorry. Don’t let my post distract from the wider topic of UHI modelling!
Hi @snigdha.jain,
I have not tested any of the tools you mentioned above however as you are on the Ladybug Tools forum I feel it’s relevant to mention the Dragonfly plugin which uses the UWG engine to run UHI simulations. I am going to link in @SaeranVasanthakumar into this conversation also as he worked quite a bit on converting UWG from Matlab to Python code.
If you want to use Grasshopper to do this you can try this example by @chris.
If you don’t have access to rhino or grasshopper you could always try to follow this example by yours truly but bear in mind this workflow is not yet perfect so might to cover geometry parameters as precisely as you would like.
