Detailed Description

This Action adds all required delayed neutron precursor variables and kernels to the problem. Since the delayed neutron precursors transport problem is pure advection, the problem is solved using discontinous Galerkin as documented in: Discontinuous Galerkin Methods for Solving Elliptic and Parabolic Equations: Theory and Implementation Note that the flow velocity must be constant when using the DGAdvection or DGTemperatureAdvection. In order to vary to flow through a user-defined function, use DGFunctionAdvection or DGFunctionTemperatureAdvection.
