A multigrid method for CutFEM and its implementation on GPU
Cu Cui, Guido Kanschat
We present a multigrid method for an unfitted finite element discretization of the Dirichlet boundary value problem. The discretization employs Nitsche's method to implement the bo…

Subsweep: Extensions to the Sweep method for radiative transfer
Toni Peter, Joseph S. W. Lewis, Ralf S. Klessen +2
We introduce the radiative transfer postprocessing code Subsweep. The code is based on the method of transport sweeps, in which the exact solution to the scattering-less radiative…
