problem of semi-transperant wall
 
Bonjour,

I'm recently running the simulation of solar radiation problem. There's no other heat resource but the sun light, and I've set a semi-transparent wall facing to the sun, but when I was going to run the circulation I got the warning shown as follow

-------------------------------------------------------------------------
Theoretical Maximum:
Sun Direction Vector: X: 0.0450431, Y: 0.304243, Z: -0.951529
Sunshine Fraction: 1
Direct Normal Solar Irradiation [W/m^2]: 1423

Warning: The neighboring cell threads (13 and 10) of semi-transparent wall zone 15 are not fluid.
This problem MUST be fixed before proceeding!
-------------------------------------------------------------------------

any suggestion would be helpful

thanks

I haven't run into this error yet, but if I were you I would do what the error message tells me.
Put a fluid next to the semi-transparent wall.

I've set the air adjacent to the semi transparent wall
just wondering why the warning was shown :confused:
