4. Construction of DF diagrams for operators in the 1er order (transport)

Conservation laws form a very important class of physics equations. If we denote by C the scalar whose conservation we wish to write (concentration, for example) and by the associated flux vector (which enables us to calculate the hourly flow of C through a given surface), the conservation of C over a volume V is written :
