#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
#   p = n * R * T / V
# where
#   p is the pressure
#   n is the amount of material in the volume (moles)
#   R is the universal gas constant
#   T is the temperature
#   V is the volume
#
# The mesh is composed of one block (2) with an interior cavity of volume 8.
#   Block 1 sits in the cavity and has a volume of 1.  Thus, the total
#   initial volume is 7.
# The test adjusts T in the following way:
#   T => T0 + beta * t
# with
#   beta = T0
#   T0 = 240.54443866068704
#   V0 = 7
#   n0 = f(p0)
#   p0 = 100
#   R = 8.314472 J * K^(-1) * mol^(-1)

#
# The mesh consists of two blocks.  Block 1 has a height and width of 1 whereas
# block 2 has a height of 2 and width of 1. A gap of 1 exists between the two
# blocks in the x direction.  Elements are 0.25 high and 1 wide.  The solution
# in block 1 is u = y and block 2 is u = 4y.
#
# Two sets of LayeredAverage values are computed.  In both cases, four
# layers are used.  In 'bounding_block1', the LayeredAverage values are computed
# on block 1 using the bounds (dimensions of block 2). In 'bounding_block2',
# the LayeredAverage values are computed on block 2 using the bounds (dimensions
# of block 1).
#
# In 'bounding_block1', since the layers are defined by the dimensions of block
# 2 only two layers appear in block one.  The values in block 1 are thus:
# 0.25 for 0<y<0.5 and 0.75 for 0.5<y<1.
#
# In 'bounding_block2', since the layers are defined by the dimensions of block
# 1 four layers appear in block two. Any place over and above the top of the
# uppermost layer is included in the uppermost layer.  Therefore, the first 3
# layers are 1/4 of the height of block 1 (0.25) whereas the 4th layer has a
# height of 1/4 of block 1 (0.25) plus the additional region in block 2 outside
# the bounds of block 1 (1.0) for a total height of 1.24.
# The values in block 2 are thus:
# 0.5 from 0<y<0.25, 1.5 from 0.25<y<0.5, 2.5 from 0.5<y<0.75, and 5.5 from
# y>0.75.

#
# There are four variables and four functions of the same name, u,v,w, and A.  The diffusion equation is solved
# for each of these variables with a boundary condition of type FunctionDirchletBC applied to a boundary
# (i.e. node set) that includes every node in the element.  Each boundary condition uses a function of type
# PiecewiseBilinear that gets its value from a file named fred.csv.
#
# fred is a matrix of data whose first row and first column are vectors that can refer to either spacial positions
# corresponding to an axis or values of time.  The remaining data are values of fred for a given row and column pair.
#
#
# Visualize fred like this:
#
#                          0 1 3  where fred is a csv file that actually looks like this    0,1,3
#                        0 0 0 0                                                            0,0,0,0
#                        1 0 1 3                                                            1,0,1,3
#                        3 0 5 7                                                            3,0,5,7
#
#  Another way to think of fred is:
#
#                                   |0 1 3| - These values can be spacial positions corresponding to
#                                             axis= 0,1, or 2, or time
#
#
#                           |0|     |0 0 0|
#     These values can be - |1|     |0 1 3| - values of fred corresponding to row-column pairs
#     time or spacial       |3|     |0 5 7|
#     positions corresponding
#     to axis= 0,1, or 2
#
#
# The parameters and possible values for the function PiecewiseBilinear are:
#
# data_file = fred.csv
# axis = 0, 1, or 2
# xaxis = 0, 1, or 2
# yaxis = 0, 1, or 2
# radial = true or false (false is default)
#
# where 0, 1, or 2 refer to the x, y, or z axis.
#
# If the parameter axis is defined, then the first row of fred are spacial position and the first column
# of fred are the values of time.
#
# If the parameter xaxis is defined, then the first row of fred are spacial positions and the first column
# of fred are the values of time ... just like defining the parameter axis.
#
# If the parameter yaxis is defined, then the first row of fred are time values and the first column of fred
# are spacial positions.
#
# If parameters axis AND EITHER xaxis or yaxis are defined together you'll get a moose error.
# i.e.
# axis = 0
# xaxis = 1
# results in an error.  So, if you use the parameter axis, don't use xaxis or yaxis.
#
# If parameters xaxis and yaxis are defined (and radial is false), then the first row of fred are spacial positions corresponding to xaxis value,
# and the first column are spacial positions corresponding to the yaxis value.
#
# If xaxis and yaxis are defined and radial is true, the first row of fred contains values
# corresponding to the radius calculated from the coordinates of each point.  Note that
# the definition of xaxis and yaxis define the "plane" of the radius.  For example,
# xaxis = 0 and yaxis = 1 means that x and y components of the point are use to
# calculate the radius.  xaxis = 1 and yaxis = 2 means that x and z components are used.
# The first column is for time in this case.  xaxis and yaxis have to be specified and
# radial = true for this to work, otherwise a MOOSE error will result.
# This was developed so that an axisymmetric function could be defined for a 3D mesh.

# Patch Test

# This test is designed to compute constant xx, yy, zz, xy, yz, and xz
#  stress on a set of irregular hexes.  The mesh is composed of one
#  block with seven elements.  The elements form a unit cube with one
#  internal element.  There is a nodeset for each exterior node.

# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
#  The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
#  zx).  This gives a uniform strain/stress state for all six unique
#  tensor components.  This displacement is again applied in the second
#  step.

# With Young's modulus at 1e6 and Poisson's ratio at 0, the shear
#  modulus is 5e5 (G=E/2/(1+nu)).  Therefore, for the mechanical strain,
#
#  stress xx = 1e6 * 1e-6 = 1
#  stress yy = 1e6 * 2e-6 = 2
#  stress zz = 1e6 * 3e-6 = 3
#  stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
#             (2 * G   * gamma_xy / 2 = 2 * G * epsilon_xy)
#  stress yz = 2 * 5e5 * 2e-6 / 2 = 1
#  stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5

# Young's modulus is a function of temperature for this test.  The
#  temperature changes from 100 to 500.  The Young's modulus drops
#  due to that temperature change from 1e6 to 6e5.

# Poisson's ratio also is a function of temperature and changes from
#  0 to 0.25.

# At the end of the temperature ramp, E=6e5 and nu=0.25.  This gives
#  G=2.4e=5.  lambda=E*nu/(1+nu)/(1-2*nu)=2.4E5.  The final stress
#  is therefore

#  stress xx = 2.4e5 * 12e-6 + 2*2.4e5*2e-6 = 3.84
#  stress yy = 2.4e5 * 12e-6 + 2*2.4e5*4e-6 = 4.80
#  stress zz = 2.4e5 * 12e-6 + 2*2.4e5*6e-6 = 5.76
#  stress xy = 2 * 2.4e5 * 2e-6 / 2 = 0.48
#             (2 * G   * gamma_xy / 2 = 2 * G * epsilon_xy)
#  stress yz = 2 * 2.4e5 * 4e-6 / 2 = 0.96
#  stress xz = 2 * 2.4e5 * 6e-6 / 2 = 1.44

# in the z-direction (the mesh was displaced so that it is aligned in such a way).
# The sub-app also does a dummy diffusion solve and then computes layered average
# in the z-direction. Those value are transferred back to the master app.

# Physically the 1D sub-app is placed in the center of the 3D mesh and is oriented

# This model tests the BoundingValueNodalDamper. The converged solution
# for u starts out in the range from 0 to 1, but after several steps,
# a volumetric source drives it to a value greater than 1, which is
# outside the range of the damper. At that point, the solution can
# no longer converge, and the model errors out with a failure to converge.
# The test verifies that the damper computes the correct value in the first
# nonlinear iteration when the solution exceeds the bounds.

# This tests the capability of the code to read input files in csv or space separated format.
# There are four variables and four functions of the same name; a,b,c, and d.  The diffusion equation is "solved"
# for each of these variables with a boundary condition of type FunctionDirchletBC applied to a boundary
# (i.e. node set) that includes every node in the element, so the solution is the boundary condition defined by the function.
#  Each boundary condition uses a function of type PiecewiseLinear that gets its value from a file,
# which could be in comma separated or space separated format.  The input file can also contain comments.
#
# The files could have the form
# 0,1,2,3 # time
# 0,4,5,6 # bc value
# for format = row
# or
# 0,0
# 1,4
# 2,5
# 3,6
# for format = column
# Values in files could be separated by white space.  See the .csv and .dat files for format examples.
#
# The value of the variables should correspond to the function.
# At time = 0, the variable = 0, at time = 1, variable = 4 and so on.
