Hi
Star CCM+ decide the sun position according to the both of Azimuth and Altitude angles ,the axes for these angles is the XY earth plane and the Z toward sky. My question is where is the centre point for those two angles ,is it on the centre of domain or in another place . Thanks in advance

Solar radiation is nearly parallel, so I assume there is no center needed.
