  1. Jeremy, The recommended method for do that is to use a rating curve. You can use the populate tool to compute a level for any flow in the expected range of flows that will occur during a hydrograph. This avoids needed to worry about latency and attenuation of the flow from the inflow to the outflow. Alan
  2. Don has reminded me that the default "Wall" boundary does have velocities of zero. I will be revising SRH-Post to treat walls as zero-velocity while wet/dry boundaries will still be scaled. In the future I hope to use both cell centered and edge values to give a more accurate representation of what SRH-2D is doing internally.
  3. Don, This changed as a result of update to SRH-2D 3.2. However, as I recall, the edge of the pier did not get assigned a zero velocity even in the old version. SRH-2D would assign values to the nodes from the cell centered values that it computes. The process used a simple averaging of the wet/active cells attached to each node. So for a pier wall, the velocity from the cell centers was mapped to the edge of the mesh. When 3.2 was released we detected that the node interpolation changed from the 3.1 and the activity mapping appeared to have an error. We asked the SR
  4. Where did your SOF file come from? Was it created when you launched SRH from inside of SMS? Which version of SMS are you using? SMS 11 used what SRH referred to as the "Full" interface. SMS 12 uses what SRH refers to as the "Custom" interface. If SMS 12.1 or SMS 12.2 are creating an incomplete SOF file, I would be very interested in getting the data files and resolving this issue as a bug.
  5. Hello. The SRH-2D simulation should be able to run from a previous project. The "sof.dat" file created by SRH-Pre will contain all the input that was processed by SRH-Pre. Looking at it or stepping through the SRH-Pre run in partial mode can give greater insight about what is not working. Another option would be to make sure you have exported the SRH input files again. That would replace all the input you have so you may want to save them for forensic reasons. Finally, if you submit your data files to the Aquaveo tech support group, we can evaluate the project to see what is
  6. Amy, Without seeing the specific geometry of your model it is hard to make to many suggestions, but I had a few thoughts. 1- Spinning down with steering (or manually) to the neap tide is a valid way to start the process. You should make sure that you really are converging when you get this value. RMA2 can continue on when it is really not converged. 2- Do you have any "puddles" forming at low tide? It is a fairly well known stability issue that RMA2 will go unstable when the water level starts to rise and puddles (wet areas that have become disconnected due to drying) start to reconnect t

      Is there any method to get land elevation for my study area ( Rosetta inlet , Egypt). in order to complete my model specification.

      please, Is there any method to transfer wave data from depth 18m to my boundary at 10 m

      Dear

      During making steering between flow and wave for implicit scheme , it has been crashed and stopped. and there is an error in diagnostic file . please check for me the attached file to know the problem?

      attached the project files and the diagnostic file.

      Please I wait your reply.(Report bug doesn't work). can you inform me how it works ( we already purchased the software so, we ask about technical hours support).

      Kind Regards

      Ali
