Try changing the under relaxation factor and specific controls to avoid the divergence in DO intensity. In simple terms , check your boundary zones if attached to solid zones it will not take into account in solar ray tracing model. In ray tracing heat flux is calculated and in DO irradaition model irradaition flux is applied to walls. Hope this may help you . In latest version also you should get converged solution.
