Abstract	The hatch corner of containership is the stress concentrated region, it is an effective way that finite element mesh (FEM) model of hatch corner intercepted from the whole ship is refined and analyzed again. In this paper, an automatic FEM refining algorithms for hatch corner is presented. The necessity of evaluating the stiffness matrix and the commonly-used construction method of transition element is presented, and the distance of the new nodes at the transition edge is computed with the linear discrete method. Computing the times of iterative according to the refining mesh size and the number of nodes on transition edge, LBC of the refining model is the displacement of the sparse mesh model boundary. Results show that the refining mesh analysis can reflect the stress change in the region with larger gradient of stress variation, thus the analysis result is better than the one obtained from global analysis.
