Abstract: The multi-dimension coupling method has advantages of high efficiency and good precision when it is used for complex fluid system. A method of multi-dimension coupling simulation was developed in this paper. Based on the proposed method, a coupling platform which is highly automatic, multi-software integrated and zooming available was developed. Several case studies were performed to verify the efficiency of the method and the platform. The results show that the proposed coupling method is valid and in agreement with the results of MPCCI. The method can also work well for more complex coupling simulation tasks.
