Hi everyone, Has anyone tried to model Radiative Transfer equation on comsol? I am stuck at defining the integral term which includes scattering. Also , how do i make my functions have 3 variable dependence as RTE has dependence on position, time and direction vector

I want to model this equation

I used Coefficient form PDE.

but i am not sure how to define s^ (direction vector)
not able to define the integration either.

how do i add integral terms to differential equations?

how can i make my function dependent on 3 variables(s, r and t)
