• Click to create a second inflow, renaming it waterinflow

• Ensure the type of the BC is Inflow in the drop-down and click to edit the properties

• Also create BCs called airoutlfow and wateroutflow both of type Outflow

Assigning Boundary Conditions:

• Select X Min in the drop-down list at the top of the BCs tab

• Highlight XMin 0 in the surface tree (the bottom-left boundary)

• Check the light grey square at the line corresponding to waterinflow in the list of boundary
conditions
