Dear Abaqus users,

in

https://docs.software.vt.edu/abaqusv2022/English/SIMACAEANLRefMap/simaanl-c-eigenbuckling.htm

one finds in Section LOADS the following note:

"Follower forces (such as concentrated loads assumed to rotate with the nodal rotation or pressure loads) lead to an unsymmetric load stiffness. Since eigenvalue extraction in Abaqus/Standard can be performed only on symmetric matrices, eigenvalue analysis with follower loads may not yield correct results."

Question: Is this statement still valid?

Thanks in advance!
