Detailed Description

Computes a linear combination of all of the estimates according to the Butcher Tableau.

The linear combination is a volumetric representation which includes both the degrees of freedom and the auxiliary variables. However, the auxiliary variables are not developing over time. In Runge-Kutta, I have estimates for the right-hand side, i.e. for the derivatives

\( \partial _t Q = F(Q) \)

This is the stuff stored in RhsEstimates. It does not comprise any auxiliary variables. So I have to copy the auxiliary variables from the last valid time step every time I reconstruct a new guess.

guard: [String] (C++ code) Sequence of predicates which determine when we compute the respective RK linear combination.

Can be empty.

Member Function Documentation

◆ get_action_set_name()

solvers.rkdg.actionsets.LinearCombinationOfEstimates.LinearCombinationOfEstimates.get_action_set_name ( self )

You should replicate this function in each subclass, so you get meaningful action set names (otherwise, it will be AbstractFVActionSet0,1,2,...).

Reimplemented from solvers.rkdg.actionsets.AbstractRungeKuttaDGActionSet.AbstractRungeKuttaDGActionSet.

Definition at line 106 of file LinearCombinationOfEstimates.py.

◆ get_body_of_operation()

solvers.rkdg.actionsets.LinearCombinationOfEstimates.LinearCombinationOfEstimates.get_body_of_operation	(	self,
		operation_name
	)

Return actual C++ code snippets to be inserted into C++ code.

See class' string constants starting with OPERATION_ for possible values of operation_name. The snippet is executed if and only if the guard returned by get_guard_of_operation() holds, i.e. the body should not evaluate the guard itself. See the section "Guard and body" in the class documentation.
