Karamba NonPrismatic Beam

I am a newbie in Karamba. 

I am trying to analyze a nonprismatic beam subjected to a distributed line load. But I have a problem in the settings. 

I attached 2 pictures .

The first one shows the general setup

The second shows the baked mesh when I used the mesh setting. 

I realized the analysis somehow does not count the vertices in the middle. When I used the model view, the beam deflects (in the blue), but the vertices that counts in the mesh and used by the analysis are the ones that are located on the boundaries (which is absurd), not in the middle. How can I solve this?

I am also confused how to set up a line distributed line load. I have the line profile (see the rhino file), but how can I use this line representing the line load with in the minus Z direction. 

What I finally want is the value of the deflection of the beam in the middle where the deflection downward is the highest considering the left and right boundaries are fixed. 

I attach the rhino file of the beam which can be used directly as element in grasshopper.

Please help and advise.

Thank you all in advance.
