I have modeled three straight pipes. Each pipes were modeled with 2 beam elements. Now I want to apply the calculated water load as line load over these elements. I inititally thought to apply this as *LOAD_SEGMENT_SET where *SET_SEGMENT were defined for the beam elements. In LSDYna manual it is said "For two-dimensional geometries, a segment is a line defined by two nodes". So, what should I put in N3 and N4. If I put zero then model puts warning message and not run. Then I tried to define like below. Also, the water load needs to be applied in global X- direction. Do you think *LOAD_NODE_POINT will be good idea but in that case, I have to apply nodal loads carefully as different nodes will be having different loads (corner one will have F*0.5 and center one will ahve F*1). Thanks.

*LOAD_SEGMENT is to apply pressure load over a triangular or quad segments. Maybe check *LOAD_BEAM.
