As seen in the Airbag Geometry section, the folder needs some initial geometry definition to start with. The first step is to create a Nastran or RADIOSS input file containing a loop of (well-oriented) 1D elements (trusses, beams, springs), for example, a rectangle.  When done, read it with HyperCrash.

To learn how to create an example input file, see the listing of the rectangle.nas file used for the example.
