Under the circumstances of Common Structure Rules for Bulk Carrier and Oil Tanker (CSR-H; Harmonized Common Structure Rules) which is on effective from July 2015, the modeling area for finite element (FE) has been extended to forward and afterward cargo hold regions of a ship, more design man-hours are required in the FE modeling than that of previous rules. In addition, it is mandatorily required to generate the fine-mesh model for hot spot zones, but the target area has been extended so extensively, more design man-hours are required for fine-mesh modeling than that of coarse mesh modeling. Moreover, the local area for fatigue analysis should be modeled with very fine-mesh. However, these kinds of FE modeling for different level of detail and different purpose of analysis are time consuming and repetitive works. In this research, we would like to introduce the auto fine mesh modeling functionality that can generate fine-mesh and very-fine mesh model from the coarse mesh model, and retrieve and restore them to coarse mesh for certain purpose by re-mesh functionality. Through this process, FE model can be managed and reused with a consistent FE model from the initial design stage to detailed design stage of a ship.
