NearestPointLayeredSideAverage

The domain is virtually divided into a number of subdomains according to the nearest points provided by users. And then the layered side average is computed for the sides on each individual subdomain separately.

Compute layered side averages for nearest-point based subdomains

Input Parameters

boundaryThe list of boundary IDs from the mesh where this boundary condition applies
C++ Type:std::vector
Options:
Description:The list of boundary IDs from the mesh where this boundary condition applies
directionThe direction of the layers.
C++ Type:MooseEnum
Options:x y z
Description:The direction of the layers.
variableThe name of the variable that this boundary condition applies to
C++ Type:std::vector
Options:
Description:The name of the variable that this boundary condition applies to

Required Parameters

average_radius1When using 'average' sampling this is how the number of values both above and below the layer that will be averaged.
Default:1
C++ Type:unsigned int
Options:
Description:When using 'average' sampling this is how the number of values both above and below the layer that will be averaged.
blockThe list of block ids (SubdomainID) that this object will be applied
C++ Type:std::vector
Options:
Description:The list of block ids (SubdomainID) that this object will be applied
boundsThe 'bounding' positions of the layers i.e.: '0, 1.2, 3.7, 4.2' will mean 3 layers between those positions.
C++ Type:std::vector
Options:
Description:The 'bounding' positions of the layers i.e.: '0, 1.2, 3.7, 4.2' will mean 3 layers between those positions.
cumulativeFalseWhen true the value in each layer is the sum of the values up to and including that layer
Default:False
C++ Type:bool
Options:
Description:When true the value in each layer is the sum of the values up to and including that layer
execute_onTIMESTEP_ENDThe list of flag(s) indicating when this object should be executed, the available options include NONE, INITIAL, LINEAR, NONLINEAR, TIMESTEP_END, TIMESTEP_BEGIN, FINAL, CUSTOM.
Default:TIMESTEP_END
C++ Type:ExecFlagEnum
Options:NONE INITIAL LINEAR NONLINEAR TIMESTEP_END TIMESTEP_BEGIN FINAL CUSTOM
Description:The list of flag(s) indicating when this object should be executed, the available options include NONE, INITIAL, LINEAR, NONLINEAR, TIMESTEP_END, TIMESTEP_BEGIN, FINAL, CUSTOM.
layer_bounding_blockList of block ids (SubdomainID) that are used to determine the upper and lower geometric bounds for all layers. If this is not specified, the ids specified in 'block' are used for this purpose.
C++ Type:std::vector
Options:
Description:List of block ids (SubdomainID) that are used to determine the upper and lower geometric bounds for all layers. If this is not specified, the ids specified in 'block' are used for this purpose.
num_layersThe number of layers.
C++ Type:unsigned int
Options:
Description:The number of layers.
pointsComputations will be lumped into values at these points.
C++ Type:std::vector
Options:
Description:Computations will be lumped into values at these points.
points_fileA filename that should be looked in for points. Each set of 3 values in that file will represent a Point. This and 'points' cannot be both supplied.
C++ Type:FileName
Options:
Description:A filename that should be looked in for points. Each set of 3 values in that file will represent a Point. This and 'points' cannot be both supplied.
sample_typedirectHow to sample the layers. 'direct' means get the value of the layer the point falls in directly (or average if that layer has no value). 'interpolate' does a linear interpolation between the two closest layers. 'average' averages the two closest layers.
Default:direct
C++ Type:MooseEnum
Options:direct interpolate average
Description:How to sample the layers. 'direct' means get the value of the layer the point falls in directly (or average if that layer has no value). 'interpolate' does a linear interpolation between the two closest layers. 'average' averages the two closest layers.

Optional Parameters

allow_duplicate_execution_on_initialFalseIn the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).
Default:False
C++ Type:bool
Options:
Description:In the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).
control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector
Options:
Description:Adds user-defined labels for accessing object parameters via control logic.
enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Options:
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
Options:
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.
