回复: 【讨论】请教hypermesh怎样实现球体的剖分啊?
哈哈哈!
至于我用的前处理GID说明文档最后面给出贴出来了。
至于ilu迭代求解器:)哈哈!那个是公司的所以……
不过我想如果搞算法的人,应该在网上可以找到,叫预条件子迭代法。比较适合对称以及高质量网格的计算中。
GiD is an interactive graphical user interface used for the definition, preparation and visualization of all the data related to a numerical simulation. This data includes the definition of the geometry, materials, conditions, solution information and other parameters. The program can also generate a mesh for finite element, finite volume or finite difference analysis and write the information for a numerical simulation program in its desired format. It is also possible to run the numerical simulation from within GiD and to visualize the results of the analysis.
GiD can be customized and configured by users so that the data required for their own solver modules may be generated.These solver modules may then be included within the GiD software system.
The program works, when defining the geometry, similar to a CAD (Computer Aided Design) system but with some differences. The most important one is that the geometry is constructed in a hierarchical mode. This means that an entity of higher level (dimension) is constructed over entities of lower level; two adjacent entities will then share the same lower level entity.
All materials, conditions and solution parameters can also be defined on the geometry without the user having any knowledge of the mesh: the meshing is done once the problem has been fully defined. The advantages of doing this are that, using associative data structures, modifications can be made to the geometry and all other information will automatically be updated and ready for the analysis run.
Full graphic visualization of the geometry, mesh and conditions is available for comprehensive checking of the model before the analysis run is started. More comprehensive graphic visualization features are provided to evaluate the solution results after the analysis run. This post-processing user interface is also customizable depending on the analysis type and the results provided. |
