How to generate shading matrix for external/self shadings

For generating and using a shading mask you don’t need to turn on “detailed radiation mode” for a zone .

If  “standard radiation mode” is selected for all zones and you generate shading/insolation mask, there will be a shading mask generated only.

If you run the simulation there is a notice in the *.log / *.lst file :

*** Notice at time        :         0.000000

    Generated by Unit     :    56

    Generated by Type     :    56

    Message               : Shading mask file *.shm  for external windows exists and will be used.

In addition, you can define a geometric shading output for checking.

In many cases, the geometric shading has a significant impact but not the geometric distribution of direct solar radiation.
