ABSTRACT: A mesh adaptation approach based on Hessian matrix is proposed to solve two dimensional heat conduction equation with coupled electron, iron and photon temperatures. Three kinds of adaptive mesh and two adaptation methods based on gradient and flux of the photon finite element solution are used. It is shown that the energy conservation error and computation efficiency of the approach are improved.
