shell_ID
|
Element identifier
(Integer)
|
nb_integr
|
Integration point number through the thickness
It corresponds to the property definition of this element. Must be equal to the number of integration points given in the shell property.
(Integer)
|
npg
|
Number of surface quadrature points. Must be set according to the formulation which is used in the shell property.
(Integer)
= 0: default, set to 1
= 1: must be used for shell formulations shell_ID =1, 2, 3, 4, 24 or Ish3n =1, 2, 31
= 3: must be used for DKT18 shell formulation (Ish3n =30)
= 4: must be used for BATOZ formulation (shell_ID =12)
|
nvars
|
Number of auxiliary internal variables. Is the number of the first user variables to be initialized for a shell. It must be less or equal to the total number of internal variables used in a user type law (NUVAR).
(Integer)
|
V1
|
1st auxiliary variable value

| 1. | It also may be necessary to complete the initial state of shells issued from a previous RADIOSS run. In this case, these values may be obtained during the previous RADIOSS Engine run, using option /STATE/SHELL/AUX/FULL. |
| 2. | It must be noticed that the contents of the blocks will not necessarily be detailed. |
| 3. | For npg = 0 or 1 and nb_integr > 0, the sequence Line 4 has to be repeated for each integration point. |
| 4. | For npg = 3 or 4, sequence Line 4 must be repeated for each quadrature point and for each integration point as follows: |
repeat for each quadrature point
repeat for each integration point
Line 4
| 5. | The initial state for shells may be defined by more than one block. |
