under construction:Undocumented Class

The GBEvolution has not been documented, if you would like to contribute to MOOSE by writing documentation, please see Documenting MOOSE. The content contained on this page explains the typical documentation associated with a MooseObject; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.

    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.

    Default:True

    C++ Type:bool

    Options:

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

  • constant_onNONEWhen ELEMENT, MOOSE will only call computeQpProperties() for the 0th quadrature point, and then copy that value to the other qps.When SUBDOMAIN, MOOSE will only call computeSubdomainProperties() for the 0th quadrature point, and then copy that value to the other qps. Evaluations on element qps will be skipped
