====== JET3D ======
3D element
===== Description =====

Element adapted to the simulation of rolling. \\ 
For cases of complete or normal orthotropicity of the rolled sheet, the numbering of nodes must be done to have the local Z axis perpendicular to the rolled sheet. \\

^Control data (4I5, 3G10.0, I5, G10.0, I5)^^
|NELEM|Number of elements|
|INDPP| 0 → No specific weight (or specific mass if NTANA = -1) \\ 1 → Specific weight taken into account (or specific mass if NTANA = -1)|
|METHD|Method for the stress matrix \\ 0 → New approach (default value) \\ 1 → Classic approach|
|ISHEAR| Index to avoid shear locking \\ 0 → Value computed by the program (Default value) \\ 1 → Value fixed to 1.0 (full integration) \\ 2 → Value fixed to 0 (reduced integration) \\ 3 → Value given by the user|
|$\beta_{12}$|Coefficients for the control of shear locking \\ = 0 if ISHEAR ≠ 3|
|$\beta_{13}$|:::|
|$\beta_{23}$|:::|
|IANGL| 0 → Use global axes \\ 1 → Use local axes defined by the angle $\alpha$ - Complete orthotropic case \\ 2  → Use local axes that coincide with intrinsic axes - Normal orthotropic case|
|ANGLE| = angle between global X axis and rolling direction if IANGL = 1 \\ = 0 else|
|MLAW| Index for the material constitutive law \\ 0 → Global approach (Default value) \\ 1 → Local approach (can call any law except laws specific to JET3D element)| 
^Only if INDPP = 1 (4G10.0)^^
|WSPE(1)| = specific weight in X direction|
|WSPE(2)| = specific weight in Y direction|
