Shaft Displacement Vs length (bending)

I am trying to measure the displacement of a shaft under theloads generated by gears. I would like to plot the displacement ofthe nodes along the axis of the shaft Vs the length of the shaft.The first problem that I encounter is that there are missing nodesalong the axis of the shaft. Is there a way to prescribe nodesalong the shaft axis so I can measure their displacements?

Is there a better way of doing this?

Thanks
