Concentrated load location in 2D wire

Suppose I have a 3D beam and I wanna apply a tip load as shown in the figure below:

I want to apply the tip load on the middle of the top edge.

The 3D simulation results look good. Below is the deformation graph:

Now I want to model it in 2D as a wire:

However, I can only apply the tip load on one end of the wire, and I cannot specify the location of the tip load (i.e. middle of the top edge).

I plotted the axial stress along the wire by creating a path of edge list:

The values agree with my theoretical solution.
Since the axial stress is negative, so I guess by default Abaqus looks at the bottom edge?
If I am understanding it correctly, the axial stress should be zero at neutral axis, positive above NA, negative below NA.

My questions are:
1. Can I specify the tip load location?
2. Is there a way I can plot the axial stress of the top edge or neutral axis?

1. No. On beam elements you can apply the point load only to the node, not any section point.
2. On solids you can use a path. On a beam it is more complicated. You have to check where the section points are located (see Users Manual) and then display the results of these points.
