LIT value is 2.3886E7
 

So my transient simulation model is an multistorey carpark with a SUN object and 2 winds at different stages.

For some unknown reasons some of the cells in my model's LIT value keep coming up as 2.3886E7, while ground floor and 1/F is way hotter than 2/F, 3/F and the roof as if the radiation passes through the blockage on 1/F itself.

Is there any easy debugging process for Phoenics?
I am running these settings:
Phoenics -VR/Core
Elliptic-Staggered
One_phase
Temperature
KECHEN
IMMERSOL (Absorption:1 Scatting:0)

Note to self
 

found the problem,

Seems like the reason for that is the grid size is too small, the software failed to recognize the floor slab as a solid cell, thus allowing the radiation to pass through
