| G3055 | FATAL ERROR: G3055 | CHECK MPC AT GRID id AND GRID id COMPONENT n |
| Cause: | An MPC Bulk Data entry defined an MPC equation without rigid body behavior. This will likely result in a loss in accuracy and incorrect results due to the generation of internal constraints. MPC equations defined with grid points which are not collocated must include the appropriate rotational terms to effect rigid body motion. | |
| Action: | Correct the MPC Bulk Data entry to include the required rotational term(s). | |
| Remarks: | See the Bulk Data section for more information. |
