H5G and HDF Error

[Jonatserrano]

Hi everyone! I’m running a simple dam breach model where I have a storage area upstream, a 2d flow area downstream, and a connector (dam) with breaching parameters. First, does anyone know if the breaching plan itself is sufficient to initiate flooding in the model or do I have to input a separate unsteady flow data (flow hydrograph)?

Also I’m having these errors. I don’t really know what they mean. Hope anyone can help 🙁

I had a similar error (see below). First time 2d model worked fine. Second model with cross sections burned into terrain and deleted 1D reach from geometry …did not work. Then I saved as a new plan, deleted steady flow data, and … unsteady 2d model “Finished Unsteady Flow Simulation” (it means everything worked fine without changing the data) !!!!

Good luck,
Pawel
