| Abstract: | The development and basic theory of Characteristic based split(CBS) algorithm are introduced in this paper.Based on the characteristic and Operator-Splitting method in partial differential equation theory,the theory frame of CBS algorithm is constructed.The relative formulation used in CBS algorithm is derived in detail and a numerical example is given to further prove the accuracy and efficiency of CBS algorithm. |
