Has anybody encountered the warning message below when conducting a damped modal analysis in ANSYS 2021 R2?
The model consists of a rectangular plate suspended by body-ground longitudinal springs attached at the corners. The springs include longitudinal damping and the plate material also has material dependent-damping (damping ratio). Removing the longitudinal damping from the springs appears to alleviate the issue, while the material damping doesn't seem to change the result.

please repost the warning message

Thank you very much Chandra Sekaran for replying. The warning message is below:
Of course, changing the Frequency Display from 'Program Controlled' to 'All' will stop the actual warning message. My real interest is in what might cause non-conjugate pairs of complex frequencies to be calculated by the Full Damped Solver.
Any help would be greatly appreciated.
