The adoption of Hermite elements with complete cubic polynomials is one way to apply the constrained interpolation profile (CIP) scheme to unstructured elements. Apart from its ability to describe complicated boundary shapes, this scheme is expected to show enhanced accuracy in the way it interpolates independent variables. In this study, although limited to two-dimensional cases, the numerical error of advection calculations with Hermite triangular elements was compared with that of the A-type CIP scheme by numerical tests and Von Neumann stability analysis. The numerical error of Hermite triangular element calculations was revealed to depend on the flow direction.
