摘要：

To date, Various types of constrained interpolation profile (CIP) analysis have been proposed. In this study. the authors first examined file calculation accuracy of two-dimensional (2-D) acoustic field analysis by the CIP-conservative semi-Lagrangian of the second-order (CIP-CSL2) method. in which values of the acoustic field and the integrals between two neighboring points are used, whereas the CIP method involves file use of the values of the acoustic field and their derivatives at grid points. The results obtained by the CIP-CSL2 method, type-M CIP method. and type-C CIP method were compared for a 2-D acoustic field. The results indicate that CIP-CSL2 analysis provides high accuracy of the same order as that of the type-C CIP method. We also investigated file run-time and memory required for this method.
