Grid generation for conical nose shpe in CFX4

zahid

Hi CFX-4 users I want to simulate flow around conical nose shape using CFX4. I generate the conical surface by revolving a line which makes 30 degrees angle with x-axis about x-axis. The problem is that the revolved suface has three edges. Fourth edge has zero lenght. CFX4 requires 4 edges to generate a structured grid. I can generate this type of grid using CFX-TASCgrid. This grid consists of five faces. Sixth face is a collapsed face. In TASCflow a boundary codition called coallescense boundary condition is available. So this problem is easily solved using TASCflow. But CFX-4 does not accept collapsed faces, furthermore theree is no coallescese boundary condition available in CFX-4. How can I solve this problem in CFX-4. Thanks
