Detailed Description

class Schema_Temps_base

This class represents a time scheme, i.e. a particular resolution algorithm that will be associated with a Probleme_base (a simple problem and not a coupling). Schema_Temps_base is the abstract class at the base of the time scheme hierarchy.

We denote n as the current time, and n+1 as the time at the end of the time step. A time scheme computes u(n+1) knowing u up to u(n). It uses u(n), but may also need past values of u, such as u(n-1), ... It may also during computation use values of u at intermediate times between n and n+1, e.g. n+1/2. nb_valeurs_temporelles counts all allocated values: n, n+1, the retained past values and the intermediate values between n and n+1. nb_valeurs_futures counts n+1 and the intermediate values between n and n+1. It is therefore the number of notches the wheels turn when advancing one time step. temps_futur(i) returns the i-th future time value. Finally temps_defaut is the time that fields must return when valeurs() is called - particularly in operators. Currently only respected by Champ_Front of boundary conditions.

See also: Equation_base Probleme_base Algo_MG_base

Abstract class from which all time schemes must derive.
