  1. When I visualise the 2D model outputs in Matlab it doesn't show any results at some of the elements. The elements are not getting dry as the water depth at the elements is enough to be wet during the entire simulation period. Over the simulation period some of these elements have result at some time steps but most of the time steps there is no result at these elements in the 2d view. Some of these elements result in zero value over the entire simulation period. I am not sure whether these elements are not resolved (e.g due to the shape of the mesh) or the resolved current speeds are less than the model precision. Would you please let me know how I can rectify this issue?
  2. During the process of converting the "map" into "mesh" and merging some of the triangles, SMS (11.2.11) removes some arcs ( to merge the triangles) but remains a few nodes which are related to the removed arcs. The nodes are eventually just connecting two arcs and will result in error in Tuflow as they create some invalid elements in the mesh. previously I had the same issue but it resolved when I used an older SMS version ( Can't recall what version I had at that time) Would you please advise which versions of SMS could be used? or alternatively if there is any other way to fix this issue. Regards, Hamid
