This paper describes a new mesh-free algorithm for computational fluid dynamics. The algorithm is based on CIVA interpolation method, which is the CIP-type cubic interpolation formulated in volume/area coordinates with tetrahedron/triangle unit and can be applicable to such mesh-free methods as the Gridless and Particle methods. The CIVA-based mesh-free methods will make it possible to simulate many kinds of problems having complex geometries and phenomena with a high accuracy, since the methods are based on a tetrahedron/triangle unit and can treat both resting and moving particles (computing points). For achieving high accuracy with the methods, it is also important to correctly evaluate particle movement. The improvement of the evaluating algorithm is another objective in this study.
