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.

◆ get_action_set_name()

exahype2.solvers.rkfd.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 AbstractRKFDActionSet0,1,2,...).

Reimplemented from exahype2.solvers.rkfd.actionsets.AbstractRKFDActionSet.AbstractRKFDActionSet.

◆ get_body_of_operation()

exahype2.solvers.rkfd.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.

Here is the call graph for this function:

◆ get_includes()

exahype2.solvers.rkfd.actionsets.LinearCombinationOfEstimates.LinearCombinationOfEstimates.get_includes ( self )

Return include statements that you need.

All of these includes will eventually end up in the header of the generated C++ code.
