XFEMPhaseTransitionMovingInterfaceVelocity

calculate the interface velocity for a simple phase transition problem.

Description

The XFEMPhaseTransitionMovingInterfaceVelocity calculates an interface velocity that is given as . The current implementation only supports the case in which the interface is moving horizontally.

Input Parameters

  • diffusivity_at_negative_level_setDiffusivity for level set negative region.

    C++ Type:double

    Options:

    Description:Diffusivity for level set negative region.

  • equilibrium_concentration_jumpThe jump of the equilibrium concentration at the interface.

    C++ Type:double

    Options:

    Description:The jump of the equilibrium concentration at the interface.

  • value_at_interface_uoThe name of the userobject that obtains the value and gradient at the interface.

    C++ Type:UserObjectName

    Options:

    Description:The name of the userobject that obtains the value and gradient at the interface.

  • diffusivity_at_positive_level_setDiffusivity for level set positive region.

    C++ Type:double

    Options:

    Description:Diffusivity for level set positive region.

Required Parameters

  • 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

Optional Parameters

  • 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.

  • 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.

  • 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).

  • seed0The seed for the master random number generator

    Default:0

    C++ Type:unsigned int

    Options:

    Description:The seed for the master random number generator

  • implicitTrueDetermines whether this object is calculated using an implicit or explicit form

    Default:True

    C++ Type:bool

    Options:

    Description:Determines whether this object is calculated using an implicit or explicit form
