Split-Cell Exponential Characteristic Transport Method for Unstructured Tetrahedral Meshes

摘要

The nonlinear, exponential characteristic (EC) method is extended to unstructured meshes of tetrahedral cells in three-dimensional Cartesian coordinates. The split-cell approach developed for the linear characteristic (LC) method on such meshes is used. Exponential distributions of the source within a cell and of the inflow on upstream faces of the cell are assumed.
