| Abstract: | The stationary monochromatic radiative transfer equation is a partial differential transport equation stated on a five-dimensional phase space. To obtain a well-posed problem, boundary conditions have to be prescribed on the inflow part of the domain boundary. |
| Keywords: | Radiative transfer Galerkin least squares Finite elements Spectral method Spherical harmonics Sparse grids |
