| In general, a mesh with a large number of small elements yields more accurate results than a mesh with fewer, larger elements. However, entering thousands of nodes and edges interactively is prohibitively slow.
|
 |
| Fortunately, the process has been largely automated, and software such as Surface95 can subdivide the faces of a model (above) into thousands of small triangles, yielding a mesh like the one shown below. |
 |
| The program uses the refinement values from the model nodes to create smaller and more numerous triangles in regions where the flow is expected to be complex. The new nodes. edges and faces are stored in a file, much larger than the model file but similar in structure. |
