Tensor Networks for Block Adaptive Thermal Radiation Transport
Alex A. Gorodetsky, Patrick D. Mullen, Aditya S. Deshpande +4
Thermal radiation transport (TRT) is computationally challenging because the photon specific intensity depends simultaneously on space, angle, and frequency, producing a high-dimen…

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…

Thermal Radiation Transport with Tensor Trains
Alex A. Gorodetsky, Patrick D. Mullen, Aditya Deshpande +4
We present a novel tensor network algorithm to solve the time-dependent, gray thermal radiation transport equation. The method invokes a tensor train (TT) decomposition for the spe…
