A Comparison of Interpolation Methods in Fast Fluid Dynamics /Author=Leonard, Eric; Qiao, Hongtao; Nabi, Saleh /CreationDate=October 19, 2021 /Subject=Multi-Physical Modeling

This paper examines the use of OpenFOAM’s cellPoint and cellPointWallModified interpolation routines in fast fluid dynamics (FFD). In addition, an arrangement of OpenFOAM’s data structures is proposed which speeds up FFD and an adjustment to FFD which incorporates the Boussinesq approximation is discussed. The findings of this paper show that the use of the cellPointWallModified interpolation routine in FFD produces results closer to reference data in higher Reynolds number flows than the use of the cellPoint interpolation routine, a result which highlights the important role that interpolation plays in the accuracy of FFD.
