BoundingBoxNodeSetGenerator
Assigns all of the nodes either inside or outside of a bounding box to a new nodeset.
Overview
The MeshGenerator allows the user to specify a bounding box that overlays the mesh domain. All of the nodes inside or outside of that bounding box are then added to a new nodeset, which is specified by the user.
Input Parameters
- locationINSIDEControl of where the nodeset is to be set
Default:INSIDE
C++ Type:MooseEnum
Options:INSIDE, OUTSIDE
Controllable:No
Description:Control of where the nodeset is to be set
- show_infoFalseWhether or not to show mesh info after generating the mesh (bounding box, element types, sidesets, nodesets, subdomains, etc)
Default:False
C++ Type:bool
Controllable:No
Description:Whether or not to show mesh info after generating the mesh (bounding box, element types, sidesets, nodesets, subdomains, etc)
Optional Parameters
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Controllable:No
Description:Set the enabled status of the MooseObject.

# Test for displacement of pinched cylinder
# Ref: Figure 10 and Table 6 from Dvorkin and Bathe, Eng. Comput., Vol. 1, 1984.
# A cylinder of radius 1 m and length 2 m (along Z axis) with clamped ends
# (at z = 0 and 2 m) is pinched at mid-length by placing point loads of 10 N
# at (1, 0, 1) and (-1, 0, 1). Due to the symmetry of the problem, only 1/8th
# of the cylinder needs to be modeled.
# The normalized series solution for the displacement at the loading point is
# w = Wc E t / P = 164.24; where Wc is the displacement in m, E is the Young's
# modulus, t is the thickness and P is the point load.
# For this problem, E = 1e6 Pa, L = 2 m, R = 1 m, t = 0.01 m, P = 10 N and
# Poisson's ratio = 0.3. FEM results from different mesh discretizations are
# presented below. Only the 10x10 mesh is included as a test.
# Mesh of 1/8 cylinder | FEM/analytical (Moose) | FEM/analytical (Dvorkin)
# |ratio of normalized disp.| ratio of normalized disp.
#----------------------|-------------------------|-------------------------
# 10 x 10 | 0.806 | 0.83
# 20 x 20 | 1.06 | 0.96
# 40 x 40 | 0.95 | -
# 80 x 160 | 0.96 | -
# The results from FEM analysis matches well with the series solution and with
# the solution presented by Dvorkin and Bathe (1984).

# Dynamic problem with plasticity.
# A column of material (not subject to gravity) has the z-displacement
# of its sides fixed, but the centre of its bottom side is pushed
# upwards. This causes failure in the bottom elements.
#
# The problem utilises damping in the following way.
# The DynamicStressDivergenceTensors forms the residual
# integral grad(stress) + zeta*grad(stress-dot)
# = V/L * elasticity * (du/dx + zeta * dv/dx)
# where V is the elemental volume, and L is the length-scale,
# and u is the displacement, and v is the velocity.
# The InertialForce forms the residual
# integral density * (accel + eta * velocity)
# = V * density * (a + eta * v)
# where a is the acceleration.
# So, a damped oscillator description with both these
# kernels looks like
# 0 = V * (density * a + density * eta * v + elasticity * zeta * v / L^2 + elasticity / L^2 * u)
# Critical damping is when the coefficient of v is
# 2 * sqrt(density * elasticity / L^2)
# In the case at hand, density=1E4, elasticity~1E10 (Young is 16GPa),
# L~1 to 10 (in the horizontal or vertical direction), so this coefficient ~ 1E7 to 1E6.
# Choosing eta = 1E3 and zeta = 1E-2 gives approximate critical damping.
# If zeta is high then steady-state is achieved very quickly.
#
# In the case of plasticity, the effective stiffness of the elements
# is significantly less. Therefore, the above parameters give
# overdamping.
#
# This simulation is a nice example of the irreversable and non-uniqueness
# of simulations involving plasticity. The result depends on the damping
# parameters and the time stepping.

# Dynamic problem with plasticity.
# A column of material (not subject to gravity) has the z-displacement
# of its sides fixed, but the centre of its bottom side is pulled
# downwards. This causes failure in the bottom elements.
#
# The problem utilises damping in the following way.
# The DynamicStressDivergenceTensors forms the residual
# integral grad(stress) + zeta*grad(stress-dot)
# = V/L * elasticity * (du/dx + zeta * dv/dx)
# where V is the elemental volume, and L is the length-scale,
# and u is the displacement, and v is the velocity.
# The InertialForce forms the residual
# integral density * (accel + eta * velocity)
# = V * density * (a + eta * v)
# where a is the acceleration.
# So, a damped oscillator description with both these
# kernels looks like
# 0 = V * (density * a + density * eta * v + elasticity * zeta * v / L^2 + elasticity / L^2 * u)
# Critical damping is when the coefficient of v is
# 2 * sqrt(density * elasticity / L^2)
# In the case at hand, density=1E4, elasticity~1E10 (Young is 16GPa),
# L~1 to 10 (in the horizontal or vertical direction), so this coefficient ~ 1E7 to 1E6.
# Choosing eta = 1E3 and zeta = 1E-2 gives approximate critical damping.
# If zeta is high then steady-state is achieved very quickly.
#
# In the case of plasticity, the effective stiffness of the elements
# is significantly less. Therefore, the above parameters give
# overdamping.
#
# This simulation is a nice example of the irreversable and non-uniqueness
# of simulations involving plasticity. The result depends on the damping
# parameters and the time stepping.

# Test for simply supported plate under uniform pressure
# One quarter of a 50 m x 50 m x 1m plate is modeled in this test.
# Pressure loading is applied on the top surface using nodal forces
# of magnitude -10 N on all nodes. This corresponds to a pressure (q) of
# -10.816 N/m^2.
# The FEM solution at (0,0), which is at the center of the full plate
# is -2.997084e-03 m.
# The analytical solution for displacement at center of plate obtained
# using a thin plate assumption for a square plate is
# w = 16 q a^4/(D*pi^6) \sum_{m = 1,3,5, ..}^\inf \sum_{n = 1,3,5, ..}^\inf (-1)^{(m+n-2)/2}/(mn*(m^2+n^2)^2)
# The above solution is the Navier's series solution from the "Theory of plates
# and shells" by Timoshenko and Woinowsky-Krieger (1959).
# where a = 50 m, q = -10.816 N/m^2 and D = E/(12(1-v^2))
# The analytical series solution converges to 2.998535904e-03 m
# when the first 16 terms of the series are considered (i.e., until
# m & n = 7).
# The resulting relative error between FEM and analytical solution is
# 0.048%.
