How to set an internal boundary condition in SWMM 5, InfoSWMM and H2OMap SWMM

How to set an internal boundary condition in SWMM 5, InfoSWMM and H2OMap SWMM

1. Make the internal boundary node a storage node
2. Set the Storage node initial depth
3. Give it a large storage area
4. Set the offset depth of the link below the storage node to the Storage Node initial depth
5. The Node depth will be at the initial depth at the start of the simulation
