Declaring the view factor to Ground
for a floor as 1, what is defined in
the user manual, produces the following error message:
** Warning ** Floor Tilt=0.0, much less than expected tilt
of 180,
for Surface=ZN01:FB, in Zone=TYPRAUMS
Having the View Factor to Ground as a value of 1.0 is not what is causing
this error message. (Warning).
This is caused by geometry specification that then calculates a tilt of
0.0. (which is normal for roofs) rather than the "normal" for
floors of 180. This could be caused by viewing the floor
coordinates from "inside" the surface (i.e. from inside the
zone) rather than from the outside OR from incorrectly specifying the
starting coordinate.
