====== JET2D ======
Plane or axisymmetric state

===== Description =====

For the axisymmetric state, the symmetry axis is Y. \\ {{  :elements:plani.png?200|}} \\
:!: If plane stress state: the element only accepts a thicknesss THICK=1 (default value) → Use forces per thickness unit F/e to solve the problem. \\ \\
Element type: 30 \\
Implemented by: S. Cescotto (1988)

|TITLE|"JET2D" in columns 1 to 5|
^ Control data (2I5) ^^
|NELEM| Number of elements |
|INDPP| 0 → No specific weight (or volumic mass if NTANA = -1) \\ 1 → Specific weight taken into account (or volumic mass is NTANA = -1)|
|ILAW| 0 → if the used material laws are those adapted only to JET2D elements \\ 1 → if the material law is a conventional 2D material law (for example, ARB2E, ARB2A, etc...)|
^Only if INDPP = 1 (3G10.0)^^
