  1. Hi, I am trying to model a similar scenario wherein I'm trying to transfer 2D flows from polygons placed on roofs of the raised buildings in the DEM to a 1D pit (Q type) on the lower ground. Basically I was trying to replicate actual conditions wherein roof will drain into gutters, then discharge to the pit on the ground. The model has polygons (2d_bc, type SX) and lines (type CN) connecting the polygon's vertex to the 1D pit. Running the model, I'm getting a TUFLOW ERROR 2050 - Lowest ZC elevation at/along SX link is above 1D node bed. Also tried using lines (2d_bc, type SX) along the cells of the roof gutters instead but I'm still getting the same error. Is there a better way to model this? Thanks! Ezra
