hmtoggle_plus1Comments
1.surf_IDex must be defined using segments associated with 4-nodes or 3-nodes shell elements (possibly void elements), and not with /SURF/SEG.
2.The volume must be closed and the normals must be oriented outwards.
3.Abscissa scale factors are used to transform abscissa units in airbag functions, for example:

where, t is the time.

where, P is the pressure.
