# Internal Volume Layered1D

Computes the volume of an enclosed area by performing an integral over a user-supplied boundary.

## Description

InternalVolumeLayered1D calculates the internal volume for the case of Layered1D. For the integration along the layer stacking direction, it uses the constant slice_height for each layer fetched from Layered1DFuelPinGeometry object.

(1) where is the total integrated volume, is the layer index, is the height of layer , and is the in-plane area of layer .

## Example Input Syntax

[./volume]
type = InternalVolumeLayered1D
fuel_pin_geometry = pin_geometry
boundary = 9
execute_on = 'initial timestep_end'
[../]
(test/tests/layered_1D/internal_volume.i)

## Input Parameters

Default:0

C++ Type:FunctionName

Description:An additional volume to be included in the internal volume calculation. A time-dependent function is expected.

• 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

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.

• component0The component to use in the integration

Default:0

C++ Type:unsigned int

Description:The component to use in the integration

• scale_factor1A scale factor to be applied to the internal volume calculation

Default:1

C++ Type:double

Description:A scale factor to be applied to the internal volume calculation

### Optional Parameters

• control_tagsAdds user-defined labels for accessing object parameters via control logic.

C++ Type:std::vector

Description:Adds user-defined labels for accessing object parameters via control logic.

• enableTrueSet the enabled status of the MooseObject.

Default:True

C++ Type:bool

Description:Set the enabled status of the MooseObject.

• 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

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).

• use_displaced_meshTrueWhether 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:True

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.
