- componentThe displacement component to consider for this kernel
C++ Type:unsigned int
Controllable:No
Description:The displacement component to consider for this kernel
- global_strain_uoThe name of the GlobalStrainUserObject
C++ Type:UserObjectName
Controllable:No
Description:The name of the GlobalStrainUserObject

GlobalDisplacementAux
AuxKernel to visualize the displacements generated by the global strain tensor
Description
The AuxKernel GlobalDisplacementAux calculates the displacement components from the global strain tensor. Optionally, it can combine the global displacement with the displacements calculated from the stress divergence kernel to provide the total displacement. It saves individual displacement components into an AuxVariable for visualization and/or post-processing purposes.
Example Input File Syntax
[./disp_y]
type = GlobalDisplacementAux
variable = disp_y
scalar_global_strain = global_strain
global_strain_uo = global_strain_uo
component = 1
[../]
An AuxVariable is required to store the displacements calculated by the AuxKernel. The name of the AuxVariable is used as the argument for the variable input parameter.
[./disp_y]
[../]
Visualization
In order to visualize the deformed shape with respect to the displacements calculated here, name the AuxVariables as disp_x, disp_y, disp_z and use some other names for the displacement variables.
Input Parameters
- blockThe list of blocks (ids or names) that this object will be applied
C++ Type:std::vector<SubdomainName>
Controllable:No
Description:The list of blocks (ids or names) that this object will be applied
- boundaryThe list of boundaries (ids or names) from the mesh where this object applies
C++ Type:std::vector<BoundaryName>
Controllable:No
Description:The list of boundaries (ids or names) from the mesh where this object applies
- check_boundary_restrictedTrueWhether to check for multiple element sides on the boundary in the case of a boundary restricted, element aux variable. Setting this to false will allow contribution to a single element's elemental value(s) from multiple boundary sides on the same element (example: when the restricted boundary exists on two or more sides of an element, such as at a corner of a mesh
Default:True
C++ Type:bool
Controllable:No
