You probably need to send that input file to the
helpdesk. Make sure the floor is listed as a
"floor".
If it is tilted too much, that could be a reason as well.
You have non-convex casting surfaces -- you can enter
Output:Diagnostics,DisplayExtraWarnings; and find out which surface that
is. Then, you have the option of splitting it into convex surfaces
or living with the shading errors.

Hi
Trying to simulate a tilted solar collector over a roof, appears a severe
error about the absorption on the floor:
** Severe **
ComputeIntSolarAbsorpFactors: Solar distribution model is set to place
solar gains on the zone floor,
** ~~~ ** but Zone ="Z
CHAM" floor cannot absorb any solar gains.
** ~~~ ** Check the solar
absorptance of the inside layer of the floor surface
construction/material.
** ~~~ ** Solar gains will be spread
evenly on all surfaces in the zone, and the simulation continues...
What could I do for making my tilted floor to absorb solar
gains?
As suggested for the error report, I check the solar absortance of the
inside layer of that floor.
That solar absortance is set to: 0.85
Does anybody have some suggestion?
There´s also a severe error on shadowing calculations:
** Severe **
DetermineShadowingCombinations: There are 1 surfaces which are casting
surfaces and are non-convex.

inaccurate. Check .shd report file for more surface shading details
