Comments

  1. The relative pressure is defined as, Prel = pressure inside of monitored volume - atmospheric pressure.
  2. surf_IDex must be defined using segments associated with 4- or 3-nodes shell elements (possibly void elements) and not with /SURF/SEG.
  3. The volume must be closed and the normals must be oriented outwards.
  4. Abscissa scale factors are used to transform abscissa units in airbag functions, for example:(1)
    F ( t ) = fct _ ID t = f ( t Ascale t )
