-----------------------------------
1. Positioning of the grains:
* genInitialPosition: function to place grains
args: + filename: name of the file to save features 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)
2. Definition of numerical and physical parameters:
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

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
