Customer received USER FATAL MESSAGE 4660 (EQX4GC). THE GEOMETRY HAS NOT BEEN DEFINED PROPERLY.

In Pre/Post, you can perform axisymmetric analysis on body of revolution parts by creating the FE model on a section plane on one side of the rotational axis. This greatly reduces the degrees of freedom (DOF) and therefore also significantly reduces solution time.

Axisymmetric analysis requires you to properly align the center of rotation and the radial axis of the axisymmetric model to the absolute coordinate system.

In the NX Nastran environment:

The center of rotation is the absolute Z-axis, and the axisymmetric plane is absolute XZ. The model must lie in the +X half of the XZ plane.

The center of rotation is the absolute X-axis, and the axisymmetric plane is absolute XY. The model must lie in the +Y half of the XY plane.

To move the model to the appropriate location for axisymmetric analysis, use the Reposition Master option. To find this option, right-click the idealized part node in the Simulation Navigator.
