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