Running A/View 2021.4. Noticed this "new" (to me?) message in the .msg file...
The model has been modified by changing the connectivity of some Markers located on Flexible bodies having more than 40 active modes. See environment variable MSC_ADAMS_SOLVER_FLEXBODY_BOOST_THRESHOLD for changing the threshold or MSC_ADAMS_SOLVER_NO_FLEXBODY_BOOST to disable this feature.
"changing the connectivity" caught my attention. Any thoughts what this is about?
