By default, the connection capability writes Ansys Neutral Format (.anf) files whenever a file is imported. A benefit of this feature is that an assembly (multiple .anf files) may be imported to create a Mechanical APDL database by properly naming and saving individual files. The commands to perform this action are shown below.

/INPUT part1.anf
/INPUT part2.anf
/INPUT part3.anf 

Mechanical APDL displays the following message after you import the second file (and any subsequent files):

You have already entered the input file utility (AUX15)

You can ignore this message.

The number of files that you can add to create a single database depends on the memory configuration of your machine.

Mechanical APDL automatically increments the entity numbers of the objects (keypoints, lines, areas, and volumes) in the subsequent .anf files by the highest object in the previous .anf files. This prevents object numbers from being duplicated in the final database.

For example, you could have numbered lines and areas in part1.anf and part2.anf like this:

When you put both into a new Mechanical APDL database, the object numbers are automatically updated like this:

This combination scheme can produce some object number gaps in the new database.
