methodology
five stages
meshing
-
Setting up the geometry is the first step in a CCM problem. In OpenFOAM the geometry and
mesh is done together and there are two utilities to generate meshes, which are the blockMesh
and the snappyHexMesh. A mesh can also be imported from a third-party product and converted
to OpenFOAM format. Also, OpenFOAM defines all meshes as three-dimensional, of course
that one- and two-dimensional and axisymmetric problems can be simulated by applying special
boundary conditions.

choice of solver
required: kinetic, in compressible and porous? therefore icoFOAM<- check this

physical properties
The physical properties of the fluid are set in the thermophysicalProperties file for compressible
flows or transportProperties for incompressible. For incompressible flows the file transportProperties
is where it is defined the fluid viscosity and transport model
The time and data output controls are defined in controlDict and it is where the time step is
defined as well as the initial time and final time and the time to save the data.

Paraview
This is the main post-processing software distributed with OpenFOAM. It is an open-source
data analysis and visualisation tool
Data processing
can be done either interactively in a 3D environment or using command line batch processing
