I think this is more a fem related issue than a material related issue. However don't know why you need a singe node as another material...
The only way to archive this i thing would be add a point to the model and mark the model as one material and the other part(s) as their own material(s). I think this option would be great also for solo points. In this way can make the single node rigid and or make springs between the the point and the object(s).
For me that would be a great improvement!
Thank you Jee Bee. It is true, maybe is FEM related problem. (It is possible to remove the post to FEM?)
I want to see the differences of stiffness and mass very locally when performing a frequency analysis. This is the aim of changing the material of one single node.
Thank you for your solution but I am not sure... I guess that adding a new point should add not only the mass and stiffness in that point, but also the material of whole part... The characteristics of two materials should be added in that point.
