|
part_ID
|
Part identifier
(Integer, maximum 10 digits)
|
part_title
|
Part title
(Character, maximum 100 characters)
|
prop_ID
|
Property identifier of the elements in the part
(Integer)
|
mat_ID
|
Material identifier of the elements in the part
mat_ID should be 0 for spring and rivet elements.
(Integer)
|
subset_ID
|
Optional: Subset identifier to which the part belongs
If omitted, the part belongs to the global model subset.
Default = global model (Integer)
|
Thick
|
Virtual thickness for shells (optional)
(Real)
Define a thickness for shells, only used to calculate gap in interfaces.
Only available for parts containing 3-node and 4-node shells.

| 1. | A part is a homogeneous element assembly. In one part, all elements are of the same type (shells, solids, beams, trusses, springs, rivet, and so on). The elements in a part refer to the same material number (mat_ID), and to the same property identifier (prop_ID). |
| 2. | Several different parts may have the same material identifier. This is also true for property and subset identifier. |
| 3. | The value of the virtual shell thickness defined on the “Thick” field supersedes the thickness defined in the shell property, if the value of the "Thick" field equals 0 in the /SHELL or /SH3N keyword. |
| 4. | The virtual thickness for shells is used to compute the gap in interface types 7, 10, 11, 18, 19 and 20; and to compute dsearch in /INTER/TYPE2 in case of Ignore=2 or Ignore=3 and dsearch=0. |
| 5. | For shell and thick shell composite parts with /PROP/SH_COMP, /PROP/SH_SANDW, /PROP/TSH_ORTH or /PROP/TSH_COMP, materials are defined directly in the property card. The failure criteria defined within these materials (for example, LAW25) are accounted for. Material referred to in the /PART card is used only for calculation of time step and contact stiffness. |
