This repository contains applications for solving Darcy flow problems, built using the IFEM library.

1. Install IFEM from https://github.com/OPM/IFEM

This is done by first navigating to a folder <App root> in which you want the IFEM applications and typing

git clone https://github.com/OPM/IFEM-Darcy

To compile, first navigate to the root catalogue <App root>.

cd IFEM-Darcy
mkdir Debug
cd Debug
cmake -DCMAKE_BUILD_TYPE=Debug ..
make

This will compile the library and the Darcy applications. The executables can be found in the bin subfolder. Change all instances of Debug with Release to drop debug-symbols, and get a faster running code.

IFEM is using cmake test system. To compile and run all regression- and unit-tests, navigate to your build folder (i.e., <App root>/IFEM-Darcy/Debug) and type

make check

The integrands of the Darcy problem are organized in the following class hierarchy:

graph TD;
    IFEM1([IntegrandBase]) --> IFEM2([HasGravityBase])
    IFEM2 --> DarcyBase
    DarcyBase --> Darcy
    DarcyBase --> DarcyAdvection
    Darcy --> DarcyTransport
    Darcy --> CompatibleDarcy
    IFEM1 --> DarcyTransportCorr

The simulation drivers are connected to the integrands as follows:

graph TD;
    IFEM1([SIM2D,SIM3D]) --> SIMDarcy
    IFEM2([SIMSolution]) --> SIMDarcy
    SIMDarcy -. has a .-> Darcy
    IFEM1 --> SIMDarcyAdvection
    IFEM2 --> SIMDarcyAdvection
    SIMDarcyAdvection -. has a .-> DarcyAdvection
    IFEM1 --> SIMDarcyTransportCorr
    SIMDarcyTransportCorr -. has a .-> DarcyTransportCorr
    IFEM3([SIMCoupled]) --> SIMDarcySchedule
    IFEM4([SIMadmin]) --> SIMDarcySchedule
    IFEM3 -. has a .-> SIMDarcy
    IFEM3 -. has a .-> SIMDarcyAdvection
