Abstract: | To improve mesh quality for KIVA-3V a method has been developed for rapid mesh generation and dynamic mesh management with moving valves for internal combustion engines.Two phases are included in rapid mesh generation:the initial mesh generation and the mesh pre-treatment.In the second step (pre-treatment),the connectivity of those cells is generated by a new algorithm added to the KIVA-3V code after the initial mesh generated.In dynamic mesh management phase,a new rezoning algorithm is developed and the basic principle is that the rezoning starts from the moving part.The movement of the adjustment is treated as an "earth quake wave" propagating to the surrounding vertexes.The amount of coordinate adjustment of the surrounding vertexes is determined by the movement of the epicenter and the distance between the vertexes and the "epicenter".Finally,a real IC engine mesh is generated and managed according to the new method.It gives a new theory and a new method for creating and managing the mesh in IC engine. |
