openfoam fvDOM热辐射输运计算

[刘雄国]

请问大家用过openfoam热辐射输运计算功能吗?
能解释一些这个RTE方程吗?

 IiEq =
            (
                fvm::div(Ji, ILambda_[lambdaI], "div(Ji,Ii_h)")  
              + fvm::Sp(k*omega_, ILambda_[lambdaI])             
            ==
                1.0/constant::mathematical::pi*omega_
              * (
                    k*blackBody_.bLambda(lambdaI)                
                  + absorptionEmission_.ECont(lambdaI)/4         
                )
            );

对应于
$$\begin{array}{}\text{(1)}& \mathrm{\nabla }\cdot \left(Ji{I}_{\lambda }\mathbf{U}\right)+k\omega I_{\lambda }=\frac{1}{\pi \omega }(k...)\end{array}$$
