From One tree to multiple tree honeybee visualisation of thermal comfort

So im trying to do a study of how thermal comfort is inside a greenhouse around trees, got this following example in the link below showing how its done with one tree only but when i want to add more trees, it became error.

Is it something i should do? I tried with grafting it and simplifying but still error, any help would be appreciated, thanks!
