Abstract: A divergence-preserving hybrid implicit–explicit finite-difference time-domain (DP-HIE-FDTD) method is proposed for accurate and efficient electromagnetic (EM) simulations. In contrast to ...

! coarse mesh (21*21) and low Re (10) in this particular case. ! Implicit SIMPLE can deal with higher Re (hundreds) but time step and ! underrelaxation factor have to be sufficiently small. And the !

Abstract: This article presents a rapid calculation approach of the leapfrog complying divergence implicit (LCDI) finite-difference time-domain (FDTD) method incorporating lumped elements for highly ...

Finite-Difference Time-Domain (FDTD) methods have become a cornerstone in the simulation of electromagnetic phenomena, enabling researchers to solve Maxwell’s equations through discretisation in both ...

A free-boundary formulation is considered for the price of American options under jump-diffusion models with finite jump activity. On the free boundary a Cauchy boundary condition holds, due to the ...
