A novel formulation for non-convex polygon mesh based on cell-based smoothed finite element method (CS-FEM) is presented for analyzing heat conduction. The major ingredient of this article include: 1) An inverse coordinate mapping method is proposed by using arbitrary polygons of shapes such as "dog", "bird", "cow" obtained from images to discretize the problem domain; 2) The Ear clipping triangulation technique is used to construct a triangular smoothing domain consisting only of field nodes; 3) The element integral is transformed into the boundary integral of triangular smoothing domain, the...
