BCs System

  • ConvectiveFluxFunctionDetermines boundary value by fluid heat transfer coefficient and far-field temperature
  • CoupledConvectiveFlux
  • CoupledConvectiveHeatFluxBCConvective heat transfer boundary condition with temperature and heat transfer coefficent given by auxiliary variables.
  • GapHeatTransferTransfers heat across a gap between two surfaces dependant on the gap geometry specified.
  • HeatConductionBC
  • CoupledPressureBCApplies a pressure from a variable on a given boundary in a given direction
  • DashpotBC
  • DisplacementAboutAxisImplements a boundary condition that enforces rotationaldisplacement around an axis on a boundary
  • InteractionIntegralBenchmarkBC
  • PresetAccelerationPrescribe acceleration on a given boundary in a given direction
  • PresetDisplacementPrescribe the displacement on a given boundary in a given direction.
  • PresetVelocity
  • PressureApplies a pressure on a given boundary in a given direction
  • StickyBCImposes the boundary condition if exceeds the bounds provided
  • ConvectiveFluxLWRBC
  • DryCaskHeatFluxApplies a boundary condition that models fuel rod in a dry cask storage system. The rod is assumed to be the center rod in an assembly of identical rods so that the peak cladding temperature is reached. This uses the Manteufel and Trodreas correlations inside the assembly and models the assembly-to-ambient flux using a single parameter.
  • GapHeatTransferLWRBC that aids with thermal contact similar to GapHeatTransfer
  • GapPerfectConductance
  • HydrogenFluxBC
  • HydrogenFluxBC_simplified
  • HydrogenPickupHydrogen flux BC that simply multiplies the time derivative of the oxide thickness by a pickup factor to get flux. Units are for H concentration in wt.ppm.
  • PostprocessorBulkCoolantBC
  • REBEKADirichletBC
  • StanNeumannBC
  • SubmodelEndBCspecial type of Preset BC that is applied only above and below the ends of a submodel, as determined by postprocessors
  • ConvectiveFluxBCDetermines boundary values via the initial and final values, flux, and exposure duration
  • DGFunctionDiffusionDirichletBC
  • DiffusionFluxBCComputes a boundary residual contribution consistent with the Diffusion Kernel. Does not impose a boundary condition; instead computes the boundary contribution corresponding to the current value of grad(u) and accumulates it in the residual vector.
  • DirichletBCImposes the essential boundary condition , where is a constant, controllable value.
  • EigenDirichletBCDirichlet BC for eigenvalue solvers
  • FunctionDirichletBCImposes the essential boundary condition , where is a (possibly) time and space-dependent MOOSE Function.
  • FunctionNeumannBCImposes the integrated boundary condition , where is a (possibly) time and space-dependent MOOSE Function.
  • FunctionPenaltyDirichletBC
  • FunctionPresetBCThe same as FunctionDirichletBC except the value is applied before the solve begins
  • LagrangeVecDirichletBCImposes the essential boundary condition , where are constant, controllable values.
  • LagrangeVecFunctionDirichletBCImposes the essential boundary condition , where components are calculated with functions.
  • MatchedValueBCImplements a NodalBC which equates two different Variables' values on a specified boundary.
  • NeumannBCImposes the integrated boundary condition , where is a constant, controllable value.
  • OneDEqualValueConstraintBC
  • PenaltyDirichletBCEnforces a Dirichlet boundary condition in a weak sense by penalizing differences between the current solution and the Dirichlet data.
  • PostprocessorDirichletBC
  • PostprocessorNeumannBC
  • PresetBCSimilar to DirichletBC except the value is applied before the solve begins
  • SinDirichletBCImposes a time-varying essential boundary condition , where varies from an given initial value at time to a given final value over a specified duration.
  • SinNeumannBCImposes a time-varying flux boundary condition , where varies from an given initial value at time to a given final value over a specified duration.
  • VacuumBC
  • VectorNeumannBCImposes the integrated boundary condition , where is a user-defined, constant vector.
  • WeakGradientBCComputes a boundary residual contribution consistent with the Diffusion Kernel. Does not impose a boundary condition; instead computes the boundary contribution corresponding to the current value of grad(u) and accumulates it in the residual vector.
