Outdoor thermal comfort on in a specific situation

The main problem here is : I have a specific wall with a certain pattern that convect and radiate particular wavelength of energy to outside environment. Since this patterns have a small dimensions ( centimetere ) ordinary softwares can not recognize them and simulate based on them and if I scale the model, other enviromental factors like wind flow near the wall, can’t be scaled and the results would be false.
What should I do?
What software or (softwares) should I apply to my work to measure the radiation of that wall and the sensible radiation of it for a human near the wall and the wind or dry air temprature near that wall in a way that the wall patterns would be considered and the indices would be for outdoor thermal comfort?
