Since its first introduction in 1966, the Finite Difference Time Domain (FDTD) method has been widely used as a tool for solving complex electromagnetic problems. For FDTD, Maxwell’s equations are ...
Finite-difference approximations for the first derivative, valid halfway between equidistant gridpoints, are in general much more accurate than the corresponding approximations, which are valid at ...
SIAM Journal on Numerical Analysis, Vol. 48, No. 4 (2010), pp. 1281-1312 (32 pages) We develop a mixed finite element method for elliptic problems on hexahedral grids that reduces to cell-centered ...
One of the common classes of equations that is encountered in several branches of science is partial differential equations. So in this article, I look at a software package called FreeFem++ that is ...
