General description of python runs:
-----------------------------------
1. Positioning of the grains:
* genInitialPosition: function to place grains
args:
+ filename: name of the file to save features of the grains
+ r: grains radius
+ rho: grains density
+ additional args can be defined to specify the repartition geometry of the grains (e.g. external radius for drops)

1. Definition of numerical and physical parameters:
* g : gravity
* $`\rho`$ : fluid density
* $`\rho_p`$ : grains density
* $`\nu`$ : kinematic viscosity
* dt : time step
* $`\alpha`$ : stabilisation coefficient
* $`\varepsilon`$ :stabilisation parameter
* $`t_{end}`$ : time stop
* g : gravity
* $$\rho$$ : fluid density
* $`\rho_p`$ : grains density
* $`\nu`$ : kinematic viscosity
* dt : time step
* $`\alpha`$ : stabilisation coefficient
* $`\varepsilon`$ :stabilisation parameter
* $`t_{end}`$ : time stop
1. Initialisation of the fluid/grains structures
1. Boudary conditions :
Ex: strong_boundaries = [("Top",2,0.),("Top",1,0.),("Top",0,0.),("Box",1,0.),("Box",0,0.)]
agrs (tuple): +Boundary name
+ Field to impose (0: u, 1: v, 2: p)
+ Value of the field
+ Field to impose (0: u, 1: v, 2: p)
+ Value of the field
1. Resolution loop
This math is inline $`a^2+b^2=c^2`$.
This is on a separate line
