DumpObjectsProblem

Single purpose problem object that does not run the given input but allows deconstructing actions into their series of underlying Moose objects and variables.

Run any input file overriding the Problem/type parameter to DumpObjectsAction and setting the Problem/dump_path parameter to the full _hit_ input file syntax path of an action to dump the individual Moose objects and variables created by the action.

After the parse and setup stage the DumpObjectsProblem will not execute the input any further. Any objects created and parameters set by the selected action will be dumped to the screen and Moose will halt execution.

Example

The input file two_block_new.i is a test for the TensorMechanics master action, an action that sets up (aux)variables, (aux)kernels, and materials for mechanics probems. Let's see if we can examine what exactly a particular action block ([./block2]) in this file sets up.

Compile the tensor_mechanics module executable and run


./tensor_mechanics-opt -i test/tests/action/two_block_new.i Problem/type=DumpObjectsProblem Problem/dump_path=Modules/TensorMechanics/Master/block2

You should obtain the output

block in this input file creates.

The AuxVariables and AuxKernels are triggered by the generate_outputs parameter, the Kernels are informed by the choice of coordinate system, as is the finite strain calculator material.

Note that this particular action creates Moose objects only for the selected blocks, while it sets up Moose variables for the set union of all blocks handled by the action.

Input Parameters

    C++ Type:std::string

    Description:Syntax path of the action of which to dump the generated syntax

Required Parameters

  • skip_additional_restart_dataFalseTrue to skip additional data in equation system for restart. It is useful for starting a transient calculation with a steady-state solution

    Default:False

    C++ Type:bool

    Description:True to skip additional data in equation system for restart. It is useful for starting a transient calculation with a steady-state solution

  • use_nonlinearTrueDetermines whether to use a Nonlinear vs a Eigenvalue system (Automatically determined based on executioner)

    Default:True

    C++ Type:bool

    Description:Determines whether to use a Nonlinear vs a Eigenvalue system (Automatically determined based on executioner)

  • error_on_jacobian_nonzero_reallocationFalseThis causes PETSc to error if it had to reallocate memory in the Jacobian matrix due to not having enough nonzeros

    Default:False

    C++ Type:bool

    Description:This causes PETSc to error if it had to reallocate memory in the Jacobian matrix due to not having enough nonzeros

  • force_restartFalseEXPERIMENTAL: If true, a sub_app may use a restart file instead of using of using the master backup file

    Default:False

    C++ Type:bool

    Description:EXPERIMENTAL: If true, a sub_app may use a restart file instead of using of using the master backup file

    Default:0

    C++ Type:unsigned int

  • solveTrueWhether or not to actually solve the Nonlinear system. This is handy in the case that all you want to do is execute AuxKernels, Transfers, etc. without actually solving anything

    Default:True

    C++ Type:bool

    Description:Whether or not to actually solve the Nonlinear system. This is handy in the case that all you want to do is execute AuxKernels, Transfers, etc. without actually solving anything

    Default:0

    C++ Type:unsigned int

    Description:The dimension of the near nullspace

Optional Parameters

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