3D CORE CALCULATION BASED ON THE METHOD OF DYNAMIC HOMOGENIZATION [PDF]
EPJ Web of Conferences, 2021 The classical two-step calculation scheme has been extensively used to perform three-dimensional deterministic core calculations thanks to its fast results. On the other hand, direct 3D transport calculations and 2D/1D Fusion methods, mostly based on the

Parallel efficiency of a boundary integral equation method for nonlinear water waves [PDF]
, 1997 We describe the application of domain decomposition on a boundary integral method for the study of nonlinear surface waves on water in a test case for which the domain decomposition approach is an important tool to reduce the computational effort.
