I try to merge some duplicate nodes, but get the message "Node 4586 and 1795 sre in the removal list and cannot be removed" So I'm stuck with some duplicate nodes. Anyone, any idea of how to get around this? Thanks fo any help
 
Hello!,
NX AdvSim takes care of node remoal automatically, then in general if you do the meshing job correctly is not neccesary to issue nodal removal command. Not having the model in hand what I will do is to remove the mesh, use a reasonable mesh density, mesh & check mesh continuity.

To check practically if your model is correctly meshed in order to assure mesh continuity you can run a modal analysis using NX NASTRAN (SOL103) and animate the first mode of vibration, if any part is not correctly attached or constrained you will see the part fly ... this is a great way of debugging your FE model.

Best regards,
Blas.
