NumbatRayleighNumber
Calculates Rayleigh number
A Postprocessor that calculates the Rayleigh number of the flow (1) where is the permeability in the flow direction, is the density contrast between the unsaturated and saturated fluids, is gravity, is the height of the mesh in the flow direction, is the porosity, is the fluid viscosity, and is the diffusion coefficient.
Input Parameters
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Description:Set the enabled status of the MooseObject.
- use_displaced_meshFalseWhether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.
Default:False
C++ Type:bool
Description:Whether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.
