How do you normally apply line load on a wall? I added a dummy frame element at the top of the wall and applied the uniform load. However, it gives me a warning that the load has not been transfeered. does the line's property need to be modified?
The simple answer here is that area elements only recognize loads applied at their nodes, or on their surface- NOT EDGES or LINES.
So if you want to get a sheet of glass that's sitting on a wall to register, the reactions from the glass must end up at the nodes of the wall. Make a fake beam, unless you want to determine a nodal load.
