Description
Returns the tensorial moment-of-inertia Ixx, Iyy, Izz, Ixy, Ixz, Iyz values for the selected entities.
Inputs
- entity_type
- The type of entity to query. Currently supported for comps, elems, mats, props, parts, assems, plies, and laminates.
- mark_id
- The ID of the mark containing the entities. Valid values are 1 and 2.
- location_flag
- Specifies the location about which the MOI is calculated. Valid values are:
- 0 - Global (0,0,0). Default.
- 1 - COG location.
- 2 - Node specified by node_id argument.
- 3 - System specified by system_id argument.
- node_id
- Specifies the node location about which the MOI is calculated if location_flag=2. Ignored otherwise.
- axes_flag
- Specifies the axes to report the MOI values relative to. Valid values are:
- 0 - Global axes. Default.
- 1 - Principal axes
- 2 - System specified by system_id argument.
- system_id
- Specifies the system ID to report the MOI values relative to if axes_flag=2. Ignored otherwise.
- reserved_1
- Reserved for future use. Must be set to 0.
- reserved_2
- Reserved for future use. Must be set to 0.
- reserved_3
- Reserved for future use. Must be set to 0.
- reserved_4
- Reserved for future use. Must be set to 0.
- lumpedmassflag
- Specifies whether to include lumped mass in the MOI calculations.
