Tīmeklis2024. gada 5. nov. · The Lagrangian description of a “system” is based on a quantity, L, called the “Lagrangian”, which is defined as: (8.5.1) L = K − U. where K is the kinetic energy of the system, and U is its potential energy. A “system” can be a rather complex collection of objects, although we will illustrate how the Lagrangian formulation is ...

Further, Eulerian models generally require emissions to be defined on a scale comparable to the model’s computational grid while Lagrangian models can define the emissions at any resolution.
