Open Boundary conditions
For each property it's possible to define a specific boundary condition. The available options are:
1 - 1D horizontal mass balance normal to the boundary
2 - An imposed value
3 - 1D vertical diffusion is added to option 1
4 - Null gradient
5 - SubModel, a value interpolated directly from the father is imposed
6 - Orlanski type boundary condition
8 - Cyclic boundary condition
By default, option 1 is assumed.
<beginproperty> BOUNDARY_CONDITION : 1 <endproperty>
By default the value assumed for the boundary is the one assumed in the intialization process of the property field (INTERIOR) the user can also specify a value for the boundary (EXTERIOR) to be set in the DEFAULTBOUNDARY keyword.
<beginproperty> BOUNDARY_INITIALIZATION : EXTERIOR DEFAULTBOUNDARY : 0. <endproperty>
