BC::Constant
This is the most commonly used standard boundary condition implementation. The name “Constant” refers to the invariance of the BC value or character along each face of the simulation domain; however, you may cause a change in the value with time by using a Numeric::Interpolator::Linear string.
The BC on each face is specified with a type string that specifies the nature of
the BC, and a val that specifies the value.
By default, all types are Dirichlet and all values are 0.0.
The complete list of BC types are below:
Dirichlet boundary condition
types can be specified with Dirichlet, dirichlet, EXT_DIR.
Neumann boundary condition
types are specified with Neumann, neumann.
Periodic boundary conditions
can be specified with Periodic, periodic, INT_DIR.
Important: Ensure that your geometry is specified to be periodic using geometry.is_periodic.
For instance, if periodic in x, set to 1 0 0
The BC values can be specified either as a number (e.g. 1.0) or using a linear interpolator
string (e.g. (0,1:2.3,-0.1)).
The number of values and types must be either 0 (for defaults), 1 (to set the same for all field components) or N (where N=number of field components).
