The module implements the basic fluid objects necessary to represent incompressible, two-phase flow. To solve these flow equations, the module offers a standard two-point flux-approximation (TPFA) method for pressure and explicit and implicit transport solvers using single-point upstream mobility weighting, which can be combined in sequential solution procedures. The incomp module was originally part of the core module, but was moved to a separate module once the software started offering solvers for more advanced fluid models.

This ad-core module contains an object-oriented framework for simulating models of industry-standard complexity. The framework uses automatic differentiation to calculate Jacobians, which makes prototyping of new models faster. When combined with the ad-blackoil module, the framework offers a variety of black-oil type models for 2 and 3-phase, compressible flow, including dissolution and vaporization effects.

The compositional module in MRST implements support for multicomponent problems where the phase behavior is either governed by a nonlinear equation-of-state, or by a tabulated equilibrium constants.
The compositional module contains both the natural variables and the overall composition formulations for two- and three-phase flow. Full capabilities for complex wells, boundary conditions and source terms are included.

The blackoil-sequential module implements sequential solvers for the same set of equations that are implemented usign a fully-implicit discretization in ad-blackoil. The solvers are based on a fractional flow formulation wherein pressure and transport are solved as separate steps. These solvers can be significantly faster than those found in ad-blackoil for many problems, especially problems where the total velocity changes slowly during the simulation.

The standard two-point flux approximation method implemented in the incomp module is not consistent and hence not convergent unless the grid is K-orthogonal. The solver may therefore give significant grid-orientation errors for anisotropic permeabilities and skew grids. The module implements a family of mimetic finite difference (MFD) methods, which give consistent discretization for incompressible (Poisson-type) pressure equations.

The module implements the MPFA-O scheme, which is an example of a multipoint flux-approximation scheme that employs more degrees of freedom when constructing the discrete fluxes across cell interfaces; this to ensure a consistent discretization with reduced grid-orientation effects.

The module implements the operator formulation of the multiscale finite-volume (MsFV) method on structured and unstructured grids in 3D. The key idea is to introduce a set of prolongation operators, defined by solving flow problems localized to dual coarse blocks. The prolongation operators are then used to define a reduced flow problem on the coarse primal grid and map unknowns computed on this grid back to the underlying fine grid. The resulting method can either be used as an approximate solver or as a global preconditioner in an iterative solver. The module is not actively developed and is offered mostly for historic reasons. Users interested in applying multiscale methods should look at the MsRSB module instead.

The module implementes the multiscale mixed finite-element (MsMFE) method on unstructured grids in 3D. The idea is the same as for the MsFV method, except that one here uses a mixed formulation in which the multiscale basis functions (prolongation operators) are associated with coarse faces rather than blocks. The method is a good approximative solver, and a robust and accurate alternative to upscaling, for incompressible flow problems. MRST was originally developed for the sole purpose of supporting the research on MsMFE methods. For several years, this module has not been actively developed.

The Multiscale Restricted-Smoothing Basis (MsRSB) method is the current state-of-the-art within multiscale methods. MsRSB is very robust and versatile can either be used as an approximate coarse-scale solver having mass-conservative subscale resolution, or as an iterative fine-scale solver that will provide mass-conservative solutions for any given tolerance. The performance of the method has been demonstrated on incompressible 2-phase flow, compressible 2 and 3-phase black oil models, as well as compositional models. It has also been demonstrated that the method can utilize combinations of multiple prolongation operators, e.g., corresponding to coarse grids with different resolutions, adapting to geological features, adapting to wells, or moving displacement fronts. At the moment, only parts of this functionality is available in the public version of the module.

Module for low- to moderate-enthalpy geothermal simulations, developed in collaboration with Marine Collignon from the University of Geneva. The module supports single-phase, single-component water and single-phase, two-component water/NaCl models. In addition to the standard conservation equations for water and NaCl mass, the models in geothermal implement an equation for conservation of energy, with possible pressure/temperature/NaCl-dependent equations of state for density and viscosity. As part of the AD library, the module can work with tabulated PVT properties.

Flow diagnostics tools are run to establish connections and basic volume estimates, and quickly provide a qualitative picture of the flow patterns in the reservoir. These methods offer a computationally inexpensive alternative to multiphase simulations to rank, compare, and validate reservoir models, upscaling procedures, and production scenarios. The flow diagnostics module contains utilities for computing time-of-flight, tracer partitioning, and measures of dynamic heterogeneity, which in turn can be used to compute well-allocation factors, drainage/sweep regions, simple estimates of recovery and net-present-value, etc.

The coarsegrid module contains extended functionality for defining coarse grids formed as a partition of an underlying fine grid. Such grids form a key part in upscaling and multiscale methods, but act almost like any standard MRST grid and can hence be passed to most of the solvers from other modules. Coarse grid generated from a partition are also useful for visualization purposes.

Many of the routines in MRST rely on detailed geometric information about the grids including cell volumes and centroids, face areas and normals, etc. Computing this information efficiently in MATLAB is not an easy task and for very large and complex grids, the builtin functionality from the core module can be too slow. The current module therefore offers C-accelerated computation of geometric grid properties (cell centroids and volumes and face centroids, areas, and normal vectors).

The core module of MRST contains functionality for reading and processing the GRID section of ECLIPSE input data, which contains information about the reservoir geometry (grid) and the petrophysical properties (permability, porosity, net-to-gross, etc).

To accelerate the processing of large models, this module offers access to grid-processing routines written in C for the Open Porous Media (OPM) initiative, which generally can be seen as the C/C++ siebling of MRST.
