gridgen使用手册(国外英文资料) Building triangulated unstructured domains is much simpler than Building From there are few restrictions on the topology of the domain: It can have any number of edges. The gridgen curve can only draw an arc of less than 180 degrees. Gridgen can now read some of the softwares graphical formats, typically including catia, pro/e, acis, etc. However, the manual says these features are optional and require additional purchase of the licence. However, the support for Iges is built in the gridgen, so you can create the geometry from other software, convert it to the Iges format, and then enter gridgen. But gridgen only supports a subset of iges. Iges probably doesnt reduce geometry. Three, to create a domain To draw the grid, you need to specify the first edge when you set up the domain. You cant immediately select the second side, and it will think that this is the first side, and you need to click next edge, and then select the second edge. The domain of the non-structural grid consists of the outer boundary and any inner boundary. Each boundary is called an edge. You must avoid the self-connecting connector. For example, a circle cannot have only one connector, otherwise it cannot be divided into a grid. Its been a long time. Shall also apply this rule seems to be in when the cylinder is divided into, namely must to the rotating cylinder surface as two 180 - degree rotation combination, below (choose bus, choose the centerline, setting Angle of 180 degrees; then rotate again, setting - 180 degrees). The create connectors on DB entities, and then create domain, are then able to build the domain. Otherwise, its always wrong. I dont know if Im doing this right? No one to consult! If you want to partition the cylinders grid, you should set his dimension to the same side as the side when setting the dimension of the base connector. Otherwise there will be errors. Each domain in gridgen represents a single boundary condition for your flow solver. Chapter
