| X7020 | FATAL ERROR: X7020 | The rotational boundary condition has a non-zero scale factor but no amplitude curve is specified. |
| Cause: | In quasi-static solutions, a multiplier curve must be supplied to define the motion. The curve must start at zero and define a non-zero curve through the pseudo-time of the simulation. This error indicates that only the constant scale factor was supplied, which is not allowed because it would imply an instantaneous introduction of the rotation. | |
| Action: | Provide a multiplier curve. | |
| Remarks: |
