### 9.1.1. Importing Multiple Meshes

It is possible in CFX-Pre to import multiple mesh file to construct an appropriate model for your simulation. Each mesh imported is represented in the Mesh part of the Outline tree by a unique identifier based on the name of the mesh file imported.

In general, a mesh file is represented by the filename of the file imported without any preceding path (for example, if you imported `C:\Directory\File.cmdb`, this will be represented in the tree as `File.cmdb`). If after transforming the filename in this way the transformed name is already present in the tree, either because this is an earlier import of the same file or another file with the same name has been imported from a different directory, the new file will be labeled with a suffix, such as `File.cmdb(1)` for example.

If multiple mesh files are transformed in such a way that the result of the transformation glues the two files together or the files are explicitly glued together, the original mesh file entries will no longer appear under the Mesh entry as file names, but the resulting Principal 3D regions will appear under a Merged Meshes item under Mesh.
