    SRH-2D Bank erosion module

    First of all, SMS does not do numerical modeling. It is for pre- and post-processing of numerical models. Second, I do not believe that the sediment transport aspect of SRH-2D has been implemented into SMS. I think it will be added in the next version, and you may be able to use it in the current beta version. Hope this helps!

    Unable to see progress window

    I have been using SRH2D for about 5 years now, and it has never shown a hydrograph while running. The graph what was taken out, showing a downward trend, was a graph of the residual. If I remember correctly, that is how much volume is "lost" out of the model. That is about as deep as I can go in describing it. Sorry.

    You should still see the 2 monitoring points in the srh2d_3.2_quickwin screen. Verify that the two points are getting wet in the model. That window used to have 3 windows inside it. They removed one, but I don't remember what version it was when they removed it.

    ADCIRC SWAN coupling in SMS

    I could be out-of-date, but SWAN is not compatible with SMS. At least it did not used to be when I was using it.

    SMS SRH2d missing entries - wrong number of N values?

    I am not talking about the BC. Redistribute the vertices in your material coverage arcs.

    SMS SRH2d missing entries - wrong number of N values?

    I have had this error before. It appears that your channel arc was from an elevation contour? Redistribute the vertices to have less along the arc. That should fix your problem. Please let me know if it works or not.
  7. I have had this error before, but can't remember what fixed it. Have you tried running each culvert individually just to see if it will run? This may be a way you can narrow down which culvert is giving you the problem. Also, make sure you have your snap preview on. If these culverts are near where you are changing something in your proposed condition, it could be possible that they are no longer on the correct element face or at the right elevation, both of which will cause problems. If I remember what it was that fixed it, I will come back and let you know.
  8. You have to go in and reassign each culvert (actually launch it) to the one it is supposed to be. Make sure you load it in as well. Not sure why when you copy it, it breaks the link to HY-8, but it does. Let me know if that does or does not work.

    Internal Boundary Conditions - Piers

    Thanks Alan!

    Internal Boundary Conditions - Piers

    I am running version 12.3.4. I have noticed that the velocity no longer goes to zero at the face of the pier. I know that with this last release, Aquaveo got rid of the "warping" effect due to the wet/dry element function, and I was wondering if this is a result of that change? Also, what are the consequences of it not going to zero? Thanks in advance!

    Scatter - Disjointed vertices

    Try re-triangulating your scatter set, and make sure your mesh is within the boundary of you scatter set.

    SRH-2D Monitor Lines

    I believe it is just a straight average.

    Local Refinement

    Sounds like refining the mesh. The best way I know to refine a mesh is to add an arc if it is a linear feature you are trying to represent, and then adjust vertices until you have the refinement you want. If it is a general area, you can place a node, right click it and select refine attributes, then make it a refine point. There are other ways to refine your mesh, but they will do it to the entire mesh. Hope this helps.

    Local Refinement

    Can you be a little more specific? Are you talking about refining scattered set data ,or mesh elements, or what?

    Monitor Line as Outlet BC

    Do you mean to have a monitor line along with an outlet? If it is just a monitor line, there will be no outflow.
