Lol. It seems the LBT forum has become an unofficial forum for Eddy (they should really consider setting up one of their own).
I don’t know anything about the Eddy components that compute MRT but, if you want to use CFD results with Ladybug Tools capabilities and surface temperatures calculated from a full EnergyPlus simulation, just do yourself a favor and use the HB UTCI Comfort Map. You can plug in a CSV of your air speeds from Eddy like you see here:
And this is going to involve way fewer Grasshopper components that together run a lot more efficienctly.
