In the partitioned coupled analysis using independent analysis of two fields, numerical values are transferred in a coupled surface which is a boundary between different fields. If a coupled surface is inconsistent, errors are generated in this transfer and the convergence of the block iteration method is highly influenced by a problem such that the numerical values which should be preserved is not preserved. Quantitative evaluation of these problems is important for practical large-scale coupled analysis. In this research, we evaluate and verify the error of the existing method concerning interface data transfer at the boundary surface for various analysis conditions and discuss how to reduce the error.
