Analysis of a continuous finite element method for \(H(\mathrm{curl},\mathrm{div})\)-elliptic interface problem
A continuous finite element method to solve the curlcurl-grad\,div interface problem in a three-dimensional polyedron domain is presented. Different anisotropic nonhomogeneous materials are allowed to occupy multiple subdomains of the domain, with the two characteristic coefficients being discontinuous from subdomain to subdomain. With respect to the regularity associated with the problem in material subdomains, the error bound in an energy norm between the exact solution and the continuous finite element solution is proved.
