Greetings!  I am seeking assistance with running a levee what-if scenario.  I am able to input the levee information and it appears that the process that adds the levee to the DEM works properly.  However, soon after the hydraulics processing box appears, a warning appears (see attachment).  I deleted the CaseOutput.ldb file, as suggested, but I end up with the same result. 

I would greatly appreciate any assistance and look forward to hearing from someone soon.  In the meantime, all the best!
