迄今为止，已经提出了各种类型的约束插值剖面（CIP）分析。在这项研究中，作者首先检验了CIP-保守二阶半拉格朗日（CIP- csl2）方法的二维（2-D）声场分析的计算精度，CIP方法使用声场值和相邻两点之间的积分，而CIP方法使用声场值及其在网格点上的导数。比较了CIP- csl2方法、m型CIP方法和c型CIP方法对二维声场的影响。结果表明，CIP- csl2分析具有与c型CIP法相同数量级的高准确度。我们还研究了该方法所需的运行时和内存。
To date, various types of constrained interpolation profile (CIP) analysis have been proposed. In this study, the authors first examined the 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 the 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 the run-time and memory required for this method.
