Inclined No Displacement Boundary Condition Action System

Set up inclined no displacement boundary conditions

Description

The InclinedNoDisplacementBCAction Action, given in the input file as simply InclinedNoDisplacementBC, is designed to simplify the input file when several variables have the same inclined no displacement boundary condition Inclined no displacement boundary condition applied in the normal component.

Example Input Syntax

[./InclinedNoDisplacementBC]
  [./right]
    boundary = right
    penalty = 1.0e8
    displacements = 'disp_x disp_y disp_z'
  [../]
  [./bottom]
    boundary = bottom
    penalty = 1.0e8
    displacements = 'disp_x disp_y disp_z'
  [../]
  [./back]
    boundary = back
    penalty = 1.0e8
    displacements = 'disp_x disp_y disp_z'
  [../]
[../]
