Comments

  1. The nb_integr should be equal to the nb_integr defined in the shell property definition.
  2. Only compatible with Ishell =1, 2, 3, 4 or Ish3n =1, 2, 31.
  3. If nb_integr ≠ 0, repeat the optional continuation lines for each integration point.
  4. The npg must be set according to the formulation, which is used in the shell property.
  5. For npg = 0 or 1 and nb_integr > 0, the optional continuation lines have to be repeated for each integration point.
  6. The value given for thickness (Thick) will be used instead of the thickness given in property or in the shell definition.
