|---|---|---|
| ROTORID | Identification number
of a rotor. No default (Integer > 0) |
|
| LTYPE | Indicates the item
type in the list references elemental set IDs, element IDs or
property IDs.
No default (Character) |
|
| IDi | IDs of sets, elements
or properties comprising the rotor. No default (Integer > 0) |
|
| AXIS | Defines grid points which define the axis of rotation. | |
| GID1, GID2 | IDs of grids

Comments
- Fixed reference frame method is adopted for 3D rotor dynamic analysis via the ROTOR Bulk Data Entry.
- Supported element types:
- 0D elements : CONM1, CONM2
- 1D elements : CBEAM, CBAR
- 3D elements : CHEXA, CPENTA, CTETRA, CPYRA
- The THRU option is supported in lists of elemental set IDs, element IDs and property IDs. Different LTYPE lists can be used together.
- 1D rotors can be defined via the ROTORG Bulk Data Entry.
- For more information, refer to Rotor Dynamics in the User Guide.
