Detailed Description

Explicit terms are terms of PDE that can be computed explicitely, ie. from the actualy known variables (see Discretization of PDE). In the overall process of solving system of equations, explicit terms are added to the right-hand side of the linear systems associated to the discretized PDE.

In this module you will find different numerical schemes associated to the discretization of PDE for face and cell based variables. The directory is organized as follow:

• cell_scalar directory contains routines associated to the discetization of PDE defined on cells
• face_vector directory contains routines associated to the discetization of PDE defined on face
