Assigning Boundary Conditions
Boundary conditions are generally defined on nodestrings but may also be defined on nodes. The default boundary condition is a closed boundary (no flow).
Deleting Boundary Conditions
Nodal Boundary Conditions
Boundary Condition Type
- None
- No Boundary Condition is assigned to this Nodestring
- Water Surface Elevation
- A Water surface elevation BC is assigned to this Nodestring. This boundary condition is normally located at the tailwater location. (However RMA2 does sometime edit the water depth at the exit boundary to satisfy the finite element equations)
- Velocity Components
- Unit Flowrate
- No Slip Condition
Boundary Angle
- Specify Flow Direction
- Perpendicular into Boundary
- Perpendicular out of Boundary
- Specified angle
Optional Parameters
- Water Density
- Include in node summary file
Boundary Condition Value
- Constant
- Transient
Nodestring Boundary Conditions
