How to get orbit plot in workbench as there are no direct results in the solution option, like total deformation and Cambell Diagram.

I tried using a user-defined result using the command option in the solution but didn't get anything.

I just typed PLORB in the command prompt. Is this the right way to get user-defined results

Hi Dealing with Rotordynamic analysis, modal or harmonic, plotting orbits (PLORB) and printing orbits characteristics (PRORB) is of primary interest.
Unfortunately, the above commands only work for beam elements, not for solid elements.
ThePLORBcommand is valid for line elements (such asBEAM188,BEAM189,PIPE288, andPIPE289).PLORBis not supported for beam elements with the warping degree of freedom activated.
Your model must also involve a rotational velocity (OMEGAorCMOMEGA) with Coriolis enabled (CORIOLIS). Beam need to be part of the rotating element for ploting orbit.
Because orbit data is written in the database, aSETcommand must be issued after thePLORBcommand to ensure proper output for subsequent postprocessing commands.
The coordinate system for displaying nodal results must be global Cartesian (RSYS,KCN= 0).PLORBis not supported if nodes are rotated in a cylindrical coordinate system.
You can use the command (APDL) option.
