<li>The 2d_bc layers use SX type connection to embed 1D networks into the 2D domain. It removes water out of the upstream cell(s) and deposits water back at the downstream cell(s). Both region and line SX links need a CN (connection) line snapped from the upstream and downstream vertex of the 1D network line to the SX boundary. <br>
