Figure 2From: Sparse tensor phase space Galerkin approximation for radiative transportExperiment 2: Convergence in incident radiation with full and sparse DOM. Reference resolution was Lref=4. Angular resolution N′ corresponds to N≈{1,2,3,4}. Reference slopes provided as visual aids only. The savings in DoFs to reach engineering accuracy of 1%–10% are about two orders of magnitude.Back to article page
