Torque converter located in automatic transmission is important role that absorb the vibration of the engine and torque conversion. To improve vehicle performance, development of the torque converter matching to advanced engine performance is essential. The torque converter consist of impeller, turbine ,reactor and complex three dimensional shape. In order to implement a fluid performance according to the characteristics of the vehicle. Final shape is determined through repeated analysis. Flow analysis of the torque converter is essential. Time required for the analysis and accuracy of the analysis is most important. The paper proves that how to minimize the space and analysis method for determining the size of the grid to maintain the accuracy of the interpretation.
