2. Also: When I am trying to use the “Prior WS Filename” as initial flow distribution method (using the results (WSE and Vel) from a previous file), my model starts empty. When using restart file, it works fine, but I need to be able to change the geometry of my model without the need for filling up the model with water to an initial WSE again and again.

Are there any trick to using this method for Initial conditions?

Thanks a lot for an informative answer.

Do you have a good answer for my next question?

When viewing the results from the simulations dam-break simulations, the hydrograph created in RasMapper (RM) (Drawing a Profile line close to the dam downstream) and the hydrograph in the “Stage Flow Hydrograph” (SFH) are different. Most of the time the results in SFH are not as smooth as the ones from RM. It also seems that the results showed in SFH are much more sensitive to changing parameters (such as timestep, max iterations), than the results in RM. I find this both using one single 2D area and using 2D/SA connections.

Where does the RM and SFH get the results from, and are any of them “more” accurate than the other?
