EID |
Unique element identification number. |
|
GA,GB |
Grid point identification numbers of connection points. (Integer > 0) |
|
CMA,CMB |
Component number of one and only one dependent translational degree of freedom in the global coordinate system assigned by you to either GA or GB. Integer equal to 1, 2, or 3, or blank. Either CMA or CMB must contain the integer and the other must be blank. |
Element identification numbers must be unique.
Forces of constraint are not recovered.
The degree of freedom selected to be dependent must have a non-zero component along the axis of the rod. This implies that the rod must have finite length.
The degree of freedom declared dependent on this entry may not be:
- Included in a single point constraint (SPC or SPC1).
- Declared a dependent degree of freedom on any other RBAR, RBE1, RBE2, RBE3, or RROD entry.
- Declared a dependent degree of freedom on an MPC set referenced by a subcase.
