ADJunctionParallelChannels1PhaseUserObject

Computes and caches flux and residual vectors for a 1-phase junction that connects flow channels that are parallel

This user object is used with the JunctionParallelChannels1Phase component. It computes the fluxes that are used in ADVolumeJunction1PhaseBC for each of the connected flow channels and the residuals that are used in ADVolumeJunctionAdvectionScalarKernel for each of the junction's scalar degrees of freedom.
