Answer:
You can use the "Create Node 'on Line'" function available in the member shortcut menu to create a node that does not divide the member.
With this type of node, a line is not divided into two lines and remains complete. The nodal parameter δ describes the relative distance to the start node of the line. By creating nodes on lines, it is possible to apply nodal loads anywhere on the line or to force an FE node.
Then, you can apply a nodal load to this node at any angle as usual.
As you can check in the results, the force acts as expected.
