Modifying the Journal Files
Following is the sample of the heading of the journal file that was added to declare the value of different parameters.
...
By relating different coordinates of the flocculation tank to the declared parameters, we can generate meshes with different geometry by just changing the heading of the journal file.
Do look at the complete script here for further understanding.
