Multigroup Thermal Radiation Transport with Tensor Trains
Aditya S. Deshpande, Patrick D. Mullen, Alex A. Gorodetsky +4
We investigate the application of tensor-train (TT) algorithms to multigroup thermal radiation transport (i.e., photon radiation transport). The TT framework enables simulations at…
