How HyperWorks Reading LS-Dyna Files with *Include or *Include_Transform

What are the rules for HyperWorks reading LS-Dyna decks having *Include or *Include_Transform? How many layers of Includes HyperWorks can read in? Does it consider the information such as node definitions in an Include file when reading another Include file in parallel with the Include file?

I have a master LS-Dyna file like below.

*Keyword

*Include_Transform

FIle_a

..

*Include_Transform

File_b

...

*End

In File_a, I include a file with nodal definition.

*Keyword

...

*Include_Transform

File_c

...

*End

In File_b, I have *DEFINE_COORDINATE_NODES using the nodes defined in File_c. HyperWorks could not find the nodes. How can I make these readable to Hyperworks?

Thanks.
