An Improved Data Exchange Algorithm Based on the Unstructured Grids

Abstract

Data exchange (load transfer) between boundaries is a key technique in multi-physics coupling numerical simulation. Based on the relationships of point and triangle in unstructured grids, an improved data exchange algorithm, namely Unstructured Panel Inside Projective Constant-Volume Tetrahedron (UPIPCVT), is proposed for higher precision. Furthermore, the achieved data of target point is calculated by tri-linear interpolation function in the projective panel, so that it makes the computation more simple. Examples show that UPIPCVT shows a good precision and computation efficiency in data exchange.
