GfsBoundaryInflowConstant imposes a constant inflow velocity on a boundary.

The syntax in parameter files is

[ GfsBoundary ] VAL

where VAL is the value of the (constant) normal velocity on this boundary. This boundary condition is identical to

Boundary {
  BcDirichlet U VAL
  BcDirichlet V 0
  BcDirichlet W 0

with U the component of the velocity normal to the boundary and (V,W) the components of the velocity tangential to the boundary.
