Abstract
In this report, we propose a variable-grid technique for the CIP method to accurately calculate sound fields with low computational costs. This technique is based on the sub-grid technique for the CIP method [6] and provides a procedure for dynamic setting of subgridded areas according to wave propagation. This report shows outlines of the CIP analysis with the variable-grid technique and basic examinations.
