The Line2-to-Point mesh-mapping algorithm for loads documented in our AIAA paper is correct. However, there is a bug in the implementation of the mapping search part of the algorithm that leads to the problems--basically, while the total integrated loads are correct, the local loads distributed along the Point elements are incorrect when the number of points elements is greater than the number of Line2 nodes.
