Finite Volume Method
Here is the link for some results coupling the Finite Volume Method with the Discrete Element Method. I study the FVM mainly for the purpose of particle-fluid coupled problems
While I was learning the pressure-velocity coupling, I found it difficult for beginners to find a proper starting point, below is a sample page created using Maple , similar to Example 5.1 in:
Versteeg, H.K. Malalasekera, W.
An introduction to computational fluid dynamics : the finite volume method / Harlow : Longman Scientific & Technical, 1995. pp106-107
The procedure used, however, is the same approach as OpenFOAM's standard PISO solver for incompressible, laminar Newtonian fluids
See: icoFoam's wiki, but here I provide much more detail than the annotated version, more detailed explanation will be added soon. The Finite Volume Method is also used in DEM coupling for fluid field calculation.
The ParaView shows the original mesh settings:

Page 3: the second corrector step

The above procedure shows what icoFoam did for the first time step, the rest steps should be clear then. Below is ParaView screenshot showing the pressure after 1 step (No interpolation).
