pb_gen_base

Basic class for problems.

coupled_problem

Synonyms: probleme_couple

Inherits from: pb_gen_base

This instruction causes a probleme_couple type object to be created. This type of object has an associated problem list, that is, the coupling of n problems among them may be processed. Coupling between these problems is carried out explicitly via conditions at particular contact limits. Each problem may be associated either with the Associate keyword or with the Read/groupes keywords. The difference is that in the first case, the four problems exchange values then calculate their timestep, rather in the second case, the same strategy is used for all the problems listed inside one group, but the second group of problem exchange values with the first group of problems after the first group did its timestep. So, the first case may then also be written like this:

Probleme_Couple pbc

Read pbc { groupes { { pb1 , pb2 , pb3 , pb4 } } }

There is a physical environment per problem (however, the same physical environment could be common to several problems).

Each problem is resolved in a domain.

Warning : Presently, coupling requires coincident meshes. In case of non-coincident meshes, boundary condition \'paroi_contact\' in VEF returns error message (see paroi_contact for correcting procedure).

Parameters:

[groupes] (type: list of List_un_pb) pour les groupes

pbc_med

Inherits from: pb_gen_base

Allows to read med files and post-process them.

Parameters:

list_info_med (type: list of Info_med) not_set
