TensorMechanicsPlasticMohrCoulombMulti
buildconstruction:Undocumented Class
The TensorMechanicsPlasticMohrCoulombMulti has not been documented. The content listed below should be used as a starting point for documenting the class, which includes the typical automatic documentation associated with a MooseObject; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.

Overview
Example Input File Syntax
Input Parameters
- 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.
- max_iterations10Maximum number of Newton-Raphson iterations allowed in the custom return-map algorithm. For highly nonlinear hardening this may need to be higher than 10.
Default:10
C++ Type:unsigned int
Description:Maximum number of Newton-Raphson iterations allowed in the custom return-map algorithm. For highly nonlinear hardening this may need to be higher than 10.
- shiftYield surface is shifted by this amount to avoid problems with defining derivatives when eigenvalues are equal. If this is larger than f_tol, a warning will be issued. This may be set very small when using the custom returnMap. Default = f_tol.
C++ Type:double
Description:Yield surface is shifted by this amount to avoid problems with defining derivatives when eigenvalues are equal. If this is larger than f_tol, a warning will be issued. This may be set very small when using the custom returnMap. Default = f_tol.
- use_custom_returnMapTrueUse a custom return-map algorithm for this plasticity model, which may speed up computations considerably. Set to true only for isotropic elasticity with no hardening of the dilation angle. In this case you may set 'shift' very small.
Default:True
C++ Type:bool
Description:Use a custom return-map algorithm for this plasticity model, which may speed up computations considerably. Set to true only for isotropic elasticity with no hardening of the dilation angle. In this case you may set 'shift' very small.
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
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<std::string>
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.
- force_preauxFalseForces the GeneralUserObject to be executed in PREAUX
Default:False
C++ Type:bool
Description:Forces the GeneralUserObject to be executed in PREAUX

Default:False
C++ Type:bool
Description:Forces the GeneralUserObject to be executed in PREIC during initial setup
- 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
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.
