"""Multilayer consolidation of unsaturated soil
Features:
- Multiple layers.
- Unsaturated vertical drainage only.
- Water and air phases.
- Material properties that are constant in time but piecewsie linear with
depth.
- Surcharge loading.
- Independent non-zero top and bottom pore air and pore water pressure
boundary conditions.
- Surcharge/Boundary Conditions vary
with time in a piecewise-linear function multiplied by a cosine
function of time.
- Surcharge can also vary piecewise linear with depth.
The depth dependence does not vary with time.
- Mulitple loads will be combined using superposition.
- Subset of Python syntax available in input files/strings allowing
basic calculations within input files.
- Output:
- Excess pore air and pore water pressure at depth
- Average excess pore air and pore water pressure between depths.
- Settlement between depths of air phase, water phase and overall.
- Charts and csv output available.
- Program can be run as script or in a python interpreter.
- Note there is no pumping or fixed pore pressure functionality.
.. warning::
The 'Parameters' and 'Attributes' sections below require further
explanation. The parameters listed below are not used to explicitly
initialize the object. Rather they are defined in either a
multi-line string or a file-like object using python syntax; the
file/string is then used to initialize the object using the
`reader` parameter. As well as simple assignment statements
(H = 1, drn = 0 etc.), the input file/string can contain basic
calculations (z = np.linspace(0, H, 20) etc.). Not all of the
listed parameters are needed. The user should pick an appropriate
combination of attributes for their analysis (minimal explicit
checks on input data will be performed).
Each 'parameter' will be turned into an attribute that
can be accessed using conventional python dot notation, after the
object has been initialised. The attributes listed below are
calculated values (i.e. they could be interpreted as results) which
are accessible using dot notation after all calculations are
complete.
Parameters
----------
H : float, optional

this program deals with normalised depth values it is important to
enter the correct H valu, as it is used when plotting, outputing
data and in normalising gradient boundary conditions (see
`bot_vs_time` below)
mvref : float, optional
Reference value of volume compressibility mv (used with `H` in
settlement calculations). Default mvref=1.0. Note this is used to
normalise all the unsaturated volume compressibilities. It is also
used in the porosity/saturation term.

(only used for pretty output). Default kwref=1.0.
Daref : float, optional
Reference value of coefficeint of transmission for the air phase

0 = Pervious top pervious bottom (PTPB).
1 = Pervious top impoervious bottom (PTIB).
dT : float, optional
Convienient normaliser for time factor multiplier. Default dT=1.0.
neig : int, optional
Number of series terms to use in solution. Default neig=2. Don't use
neig=1.
dTw : float
Vertical reference time factor multiplier for water phase.
dTw is calculated with the chosen reference values of kw and mv:
dTw = kwref /(mvref*gamw) / H ^ 2
dTa : float
Vertical reference time factor multiplier for air phase.
dTa is calculated with the chosen reference values of Da and mv:
dTa = Daref / (mvref) / (wa/(R*T)/ua_ / H ^ 2. Where wa=molecular

in the net normal stress (dsig-dua), PolyLine(depth, m1ka).
m1kw : PolyLine
Normalised coefficient of water volume change with respect to a change

Notes
-----
**Gotchas**
All the loading terms e.g. surcharge_vs_time, surcharge_vs_depth,
surcharge_omega_phase can be either a single value or a list of values.
The corresponding lists that define a load must have the same length
e.g. if specifying multiple surcharge loads then surcharge_vs_time and
surcharge_vs_depth must be lists of the same length such that
surcharge_vs_time[0] can be paired with surcharge_vs_depth[0],
surcharge_vs_time[1] can be paired with surcharge_vs_depth[1], etc.

change in the matric suction.

- :math:`\\overline{u}_a` is the absolute air pressure.
:math:`\\overline{u}_a = u_{atm}+u_a`.
- :math:`u_{atm}` is absolute atmospheric air pressure.
- :math:`\\gamma_w` is the unit weight of water.
- :math:`Z` is the nomalised depth (:math:`Z=z/H`).
- :math:`H` is the total height of the soil profile.
- :math:`T` is the absolute temperature in kelvin.
- :math:`\\omega` is the molecular mass of air often taken as
29e-3 kg/mol.
- :math:`R` is the universal gas constant 8.314 J/(mol.K).
**Governing equation**
Overall strain :math:`\\varepsilon` is the sum of the air strain,
:math:`\\varepsilon_a` and the water strain :math:`\\varepsilon_w`:
.. math::
\\varepsilon = \\varepsilon_a + \\varepsilon_w
The water and air strain components are:
.. math::
\\varepsilon_a =
m_{1k}^a\\left({\\sigma - u_a}\\right)
+ m_2^a\\left({u_a - u_w}\\right)
.. math::
\\varepsilon_w =
m_{1k}^w\\left({\\sigma - u_a}\\right)
+ m_2^w\\left({u_a - u_w}\\right)
Both pore air and pore water pressures are functions of normalised depth
:math:`Z` and time :math:`t`, :math:`u\\left({Z, t}\\right)`. The water
and air phase partial differential equations are:
.. math::
\\left({\\overline{m}_{1k}^w - \\overline{m}_2^w}\\right) u_a,_t
+ \\overline{m}_2^w u_w,_t
+ dT_w\\left({\\overline{k}_w u_w,_Z}\\right),_Z
= \\overline{m}_{1k}^w \\sigma,_t
.. math::
\\left({\\overline{m}_{1k}^a
- \\overline{m}_2^a
- \\frac{\\left({1-S}\\right)n}{\\overline{u}_a m_{\\textrm{ref}}}
}\\right) u_a,_t
+ \\overline{m}_2^a u_w,_t
+ dT_a\\left({\\overline{D}_a u_a,_Z}\\right),_Z
= \\overline{m}_{1k}^a \\sigma,_t
where
.. math::
dT_w = \\frac{k_{w\\textrm{ref}}}
{H^2 m_{v\\textrm{ref}} \\gamma_w}
.. math::
dT_a = \\frac{D_{a\\textrm{ref}}}
{\\left({\\omega R T}\\right)
\\overline{u}_a m_{\\textrm{ref}}}
The overline notation represents a depth dependent property normalised
by the relevant reference property. e.g.
:math:`\\overline{k}_w = k_w\\left({z}\\right) / k_{w\\textrm{ref}}`.
A comma followed by a subscript represents differentiation with respect to
the subscripted variable e.g.
:math:`u,_Z = u\\left({Z,t}\\right) / \\partial Z`.
**Non-zero Boundary conditions**
The following two sorts of boundary conditions for the air and water
phases can be modelled independently using:
.. math::
\\left.u\\left({Z,t}\\right)\\right|_{Z=0} = u^{\\textrm{top}}\\left({t}\\right)
\\textrm{ and }
\\left.u\\left({Z,t}\\right)\\right|_{Z=1} = u^{\\textrm{bot}}\\left({t}\\right)
.. math::
\\left.u\\left({Z,t}\\right)\\right|_{Z=0} = u^{\\textrm{top}}\\left({t}\\right)
\\textrm{ and }
\\left.u\\left({Z,t}\\right),_Z\\right|_{Z=1} = u^{\\textrm{bot}}\\left({t}\\right)
The boundary conditions are incorporated by homogenising the governing
equation with the following substitution:
.. math::
u\\left({Z,t}\\right)
= \\hat{u}\\left({Z,t}\\right) + u_b\\left({Z,t}\\right)
where for the two types of non zero boundary boundary conditions:
.. math::
u_b\\left({Z,t}\\right)
= u^{\\textrm{top}}\\left({t}\\right) \\left({1-Z}\\right)
+ u^{\\textrm{bot}}\\left({t}\\right) Z
.. math::
u_b\\left({Z,t}\\right)
= u^{\\textrm{top}}\\left({t}\\right)
+ u^{\\textrm{bot}}\\left({t}\\right) Z
**Time and depth dependence of loads/material properties**
Soil properties do not vary with time.
Loads are formulated as the product of separate time and depth
dependant functions as well as a cyclic component:
.. math:: \\sigma\\left({Z,t}\\right)=
\\sigma\\left({Z}\\right)
\\sigma\\left({t}\\right)
\\cos\\left(\\omega t + \\phi\\right)
:math:`\\sigma\\left(t\\right)` is a piecewise linear function of time
that within the kth loading stage is defined by the load magnitude at
the start and end of the stage:
.. math::
\\sigma\\left(t\\right)
= \\sigma_k^{\\textrm{start}}
+ \\frac{\\sigma_k^{\\textrm{end}}
- \\sigma_k^{\\textrm{start}}}
{t_k^{\\textrm{end}}
- t_k^{\\textrm{start}}}
\\left(t - t_k^{\\textrm{start}}\\right)
The depth dependence of loads and material property
:math:`a\\left(Z\\right)` is a piecewise linear function
with respect to :math:`Z`, that within a layer are defined by:
.. math::
a\\left(z\\right)
= a_t + \\frac{a_b - a_t}{z_b - z_t}\\left(z - z_t\\right)
with :math:`t` and :math:`b` subscripts representing 'top' and 'bottom' of
each layer respectively.
