• This paper concerns the cubic interpolation with volume/area coordinates (CIVA) method, which is an extension of the cubic interpolation profile (CIP) to a triangular or tetrahedral mesh system, implemented in an unstructured and fixed (Eulerian) mesh-based finite-volume solver. First, we briefly explain the accuracy of and the results of stability analysis by CIVA. Then, to demonstrate the accuracy and robustness of the algorithm, we solve two-dimensional benchmark problems of incompressible lid-driven recirculating flow in square and triangular cavities. In addition, a two-dimensional vortex-driven flow is solved in order to analyze the conservative property of CIVA. Finally, an example of an industrial application of CIVA method is described. These numerical experiments demonstrate the high capability of the method and that it is sufficiently robust for complex industrial applications.
