 Let us illustrate the structure of the executable python files with a two dimensional deposit of grains in a fluid. This test case is provided in the [testcases/depot-2d/depot.py](https://git.immc.ucl.ac.be/fluidparticles/migflow/blob/master/testcases/depot-2d/depot.py) file.
 
-Some steps have to be followed in order to properly define the application you want to solve with the MigFlow Software.
+Several steps are required to properly define the problem you want to solve with the MigFlow Software.
 
 1. Set the problem parametres.
 
-  In an application, many variables are required to define :

 2. Define the matrix of the grains positions and actually create the grains at these positions
