======================================
Color model -- Basic Analysis
======================================
The basic analysis routine for the LBPM color model logs a time series
of averaged information to the space-delimited CSV file ``timelog.csv``.
The ``analysis_interval`` key should be specified to control the interval at
to perform basic analysis, which corresponds to the number of simulation timesteps
to perform between analyses. The basic analysis routine is designed to
be lightweight so that it can be performed frequently, and it is almost always
useful to enable it. Results will be immediately logged
to ``timelog.csv`` which can be used to assess whether or not the simulation is
behaving as expected. Furthermore, the analysis framework will check
simulation measures to verfiy that no ``NaN`` are detected for the fluid
pressure and flow rate.
The list of measures logged to ``timelog.csv`` are defined as follows.
The region of space occupied by the wetting fluid is determined from the
phase indicator field, :math:`\Omega_w:\phi<0`
* ``sw`` -- water saturation (fluid component 2)
* ``krw`` -- water effective permeability
* ``krw`` -- effective permeability for fluid w
* ``krn`` -- effective permeability for fluid n
* ``krwf`` -- effective permeability for fluid w (with film uncertainty estimate)
* ``krnf`` -- effective permeability for fluid n (with film uncertainty estimate)
* ``vw`` -- speed for the non-wetting fluid
* ``vn`` -- speed for the wetting fluid
* ``force`` -- magnitude for effective driving force
* ``pw`` -- average pressure for fluid w
* ``pn`` -- average pressure for fluid n
* ``wet`` -- total solid wetting energy
More comprehensive analysis is performed in the ``subphase`` analysis module.

======================================
Color model -- Subphase Analysis
======================================
The subphase analysis routine for the LBPM color model logs a time series
of averaged information to the space-delimited CSV file ``subphase.csv``.
The ``subphase_analysis_interval`` key should be specified to control the interval at
to perform basic analysis, which corresponds to the number of simulation timesteps
to perform between analyses. The subphase analys routine performs the following functions
* analyzes the connectivity of fluid phases using a connected components algorithm
* constructs iso-surfaces to represent interfaces within the system
* computes averages of physical quantities based on the defined entities
Since it is more computationally expensive to carry out these operations compared to the
basic analysis, it may be useful to choose ``subphase_analysis_interval`` to be larger than
``analysis_interval``. Nevertheless, since analysis is performed in memory, it is orders of
magnitude faster than to analyze data *in situ* rather than writing fields to disc. Monitoring
the performance in MLUPS provides an easy way to tune the analysis interval so that the
overall simulation performance is not subject to significant penalties.
There are three main entities that are constructed for subphase analysis
* :math:`\Omega_w:\phi<0` : region of space filled by fluid w
* :math:`\Omega_n:\phi<0` : region of space filled by fluid n
* :math:`\Omega_i: |\nabla \phi|<0 > \epsilon` : region of space for the interface region
The phase regions are defined identical to what is reported in ``timelog.csv``.
The interface region is defined explicitly as the portion of space where
significant composition gradients are present. For each entity, sub-entities are
constructed by running a connected components algorithm on the set. This is done to
separate the connected part of the phase from the disconnected part. This subset operation
is performed by identifying the largest connected component (based on volume)
and denoting this as the connected part of that region. The remaining portion of the
phase is lumped into a disconnected sub-entity. Subphase analysis is therefore performed
for the following six entities
* ``wc`` -- connected part of phase w
* ``wd`` -- disconnected part of phase w
* ``nc`` -- connected part of phase n
* ``nd`` -- disconnected part of phase n
* ``ic`` -- connected part of interface region
* ``id`` -- disconnected part of interface region
For each entity :math:`\Omega_k` with :math:`k\in\{wc,wd,nc,nd,ic,id\}`
an isosurface is constructed to approximate the boundary of the region,
:math:`\Gamma_k`. Once each region is identified, the following measures are determined
**Geometric invariants**
* Volume -- :math:`V_k=\int_{\Omega_k} dV`
* Surface area -- :math:`A_k=\int_{\Gamma_k} dS`
* Integral mean curvature -- :math:`H_k=\int_{\Gamma_k} \frac 12 (\kappa_1 + \kappa_2) dS`
* Euler characteristic -- :math:`\chi_k= \frac{1}{4\pi} \int_{\Gamma_k} \kappa_1 \kappa_2 dS`
**Conserved quantities**
* Total mass within the region :math:`M_k=\int_{\Omega_k} \rho dV`
* Total momentum within the region :math:`\mathbf{P}_k=\int_{\Omega_k} \rho \mathbf{u} dV`
* Total kinetic energy within the region :math:`K_k=\frac 12 \int_{\Omega_k} \rho \mathbf{u} \cdot \mathbf{u} dV`
**Thermodynamic quantities**
* Pressure -- :math:`p_k=\frac{1}{V_k}\int_{\Omega_k} p dV`
* Solid wetting energy -- :math:`\gamma_s=\int_{\Gamma_s}\gamma dS`
* Viscous dissipation -- :math:`\Phi_k=\int_{\Omega_k}\bm{\varepsilon} : \nabla \mathbf{u} dV`
The total solid wetting energy is determined by integrating the interfacial stresses in the
immediate vicinity of the solid surface :math:`\Gamma_s`. The integral of the
dissipation function is determined based on the viscous stress tensor, denoted by :math:`\bm{\varepsilon}`.
The full list of measures are associated with the labels in ``subphase.csv``
