Issue SHPP,ON or n SHPP,WARN to reactivate, if desired. nn *** ERROR *** CP = 1.656 TIME= 22:19:48n There is at least 1 small equation solver pivot term (e.g., at the AZ n degree of freedom of node 12321). Please check for an insufficiently n constrained model.nnI am trying to simulate a model in magnetostatics. I keep getting this error. Please help!n

There is no bonded contact for edge flux (AZ DOF) formulated emag elements.nAnother thing is we typically make the external surface(s) of enclosures flux parallel (constrain AZ=0). This approximates the infinite extension of the surrounding domain beyond external boundaries.nnBest,nBilln
January 23, 2021 at 5:01 pmjaydSubscriberI did make the enclosure a flux parallel. Also when i track down the node by id I get the node in the empty space (i.e. air) rather than on any body. Also I made the different parts of the model by slicing a single body. So is it possible for them to not have shared topologies?n
