Hi mike

I extracted a mapping vector using NOD2BCS and the resulting figure appeared as shown. It seems to map excluding fixed points starting from [2220,1]. What I'm curious about is what the values on both sides mean. Just like in the figure, there are fixed nodes at both the 200th and 800th positions, but in the mapping vector, all the values seem to be gathered towards the end. Isn't NOD2BCS supposed to provide the relationship between node IDs and the degrees of freedom (DOF) used by the solver?

I'm using a student license, so I can't access education sources provided by Ansys. I've also searched the internet, but I can't find the information I'm looking for. It would be greatly appreciated if you could provide a more detailed explanation on how to match the DOF of the stiffness matrix with the node IDs for F=Kx calculation, though I know it might be a hassle.

Deho
