Function/Subroutine Documentation

◆ system_execute_algorithm()

subroutine, public system_oct_m::system_execute_algorithm ( class(system_t), intent(inout) this )

perform one or more algorithmic operations

The following subroutine takes a system and performs as many algorithmic operations as possible on the system until a barrier is reached. There are two types of barriers:

explicit barriers, implemented using the barrier_t type
the couplings update

The couplings update is always considered a barrier, even if the update was successful. This is to allow other system to also update their couplings with this system before it moves on to the next operations.

Definition at line 337 of file system.F90.

◆ system_reset_iteration_counters()

subroutine, public system_oct_m::system_reset_iteration_counters	(	class(system_t), intent(inout)	this,
		integer, intent(in)	accumulated_iterations
	)

Definition at line 463 of file system.F90.

◆ system_create_interactions()

recursive subroutine, public system_oct_m::system_create_interactions	(	class(system_t), intent(inout)	this,
		class(interactions_factory_abst_t), intent(in)	interaction_factory,
		class(partner_list_t), intent(in), target	available_partners
	)

create the interactions of the system

Given a list of available partners, this routine creates all the supported interactions between the system and the partners. To do so, it uses an interaction factory. It also initializes all the interactions (calling system_t::init_interaction() and interaction_partner_t::init_interaction_as_partner())

Note: This routine also creates the ghost interactions between the system and all available partners. Any class overriding this method must make sure ghost interactions are properly created or the framework might not work correctly.

Parameters

[in,out]	this	system for which interactions are created.
[in]	interaction_factory	factory that creates the actual interactions
[in]	available_partners	a (hierarchical) list of available partners

Definition at line 517 of file system.F90.

◆ system_update_couplings()

logical function system_oct_m::system_update_couplings ( class(system_t), intent(inout) this )

private

Update the couplings (quantities) of the interaction partners.

This function loops over all interactions and the corresponding interaction partners and attempts to update their couplings to the requested iteration. It returns true if all couplings have been successfully updated.

Definition at line 694 of file system.F90.

◆ system_update_interactions()

subroutine system_oct_m::system_update_interactions ( class(system_t), intent(inout) this )

private

Attempt to update all interactions of the system.

First we try to update the systems own quantities required for the interaction, and then try to update the interaction itself.

◆ system_init_iteration_counters()

subroutine, public system_oct_m::system_init_iteration_counters ( class(system_t), intent(inout) this )

Initialize the iteration counters of the system and its interactions, algorithms and quantities.

Note that th iteration counters for interactions, and on-demand quantities are initialized to one iteration before the algorithm iteration counter. This is necessary, as the interactions and on-demand quantities first need to be updated.
