Regarding Node based Submodeling

Hello Everyone,


I am trying to understand how does node based submodeling work in abaqus? I am not able to comprehend how to transfer nodal outputs from some other FEM package so as to perform submodeling in Abaqus? Any help in this regard is highly appreciated.

I have gone through Abaqus manual to see about it but unfortunately I could not figure it out. Detailed problem statement is as follows- I have conducted a nonlinear analysis on a global model (dimensions of the order of mm) with a particular geometry and when I am trying to extract nodal data in the desired region (submodel dimensions are of the order of 100 microns), I am getting only two to five relevant nodes and I need to map these nodal outcomes to approximately 100 nodes in the submodel.
