VacuumBC
Vacuum boundary condition for diffusion.
Vacuum is defined as no incoming flux from outside the boundary. This is a common approximation in reactor physics where beyond a certain distance from a nuclear system, we assume that while neutrons may still leave the system, they will not come back.
The contribution to the residual is:
where is the domain definition and is the test function.
Example input syntax
In this input, a VacuumBC is used to impose a 0 incoming flux boundary condition in a diffusion problem in a RZ geometry problem on the top boundary for variable u.
