Why ABAQUS cannot do parallelization in buckling analysis?

Hi,

Does anybody have an idea why ABAQUS cannot do parallelization in eigenvalue buckling analysis? Thanks.

Every time a buckling analysis is performed in ABAUQS using parallelization, following warning message pops out:

"Buckle option is not supported for element loop parallelization. If you have specified element loop parallelization, it will be turned off for this analysis."
