In this study, we present three dimensional temperature field analysis considering an embedded body based on the fictitious domain FEM. As the governing equation, the steady and the unsteady heat transfer equations are introduced, and the finite element method is applied to discretize the governing equations in space. The Lagrange multiplier method is applied to consider boundary condition on the boundary of the embedded domain. In addition, the search of nodal points of embedded domain in the background meshes is carried out in the finite element analysis, and this is one of the feature in this study.
