Not equal number of mesh for ladybug recolor mesh

Hi guys,

I am doing a master thesis project, and plan to do wind simulation for indoor space through the butterfly plugin, but I have a problem with visualization results (photo), the building model is not a box. do you think the wind simulation must be in a shoebox model?
what should I do to fix it?

Thank you so much!

Looks like you probably have to use the native Grasshopper “Mesh Join” component to join those two meshes into one before you plug them into that component.
