I am currently working on a project where I would like to be able to change which node is the master node for my flexible body. Is there a way to do this in ADAMS?
As you know a mnf is a "simplification" of your original FE model that is based on the Eigen solution. All modes are "overlayed" to create a form that matches exactly at the dedicated interface nodes which means the chosen nodes and the solution are dependent from each other.
For all other nodes in between the solution is kind of "not exact". As a consequence it wouldn't be very smart to create a mnf without interface nodes and just use any arbitrary nodes in between.
BTW: For the same reason the stress recovery from mnf's is not as exact as for example a Nastran SOL400 run.
