Detailed Description

Store the maximum eigenvalue over all grid cells of a patch.

The action set runs after the final linear combination of a Runge-Kutta step, i.e. it sees the solution of the next time step in solver._patch. It stores the maximum eigenvalue in solver._max_eigenvalue, from where exahype2.api.rkfd4.actionsets.ComputeTimeStepSize reduces it into the next time step size.

Constructor & Destructor Documentation

◆ init()

exahype2.api.rkfd4.actionsets.ComputeMaxEigenvalue.ComputeMaxEigenvalue.__init__	(	self,
		solver,
		guard
	)

Parameters

solver	exahype2.api.Solver Has to have an exahype2.api.rkfd4.CentralDifferencesWithRungeKutta with adaptive time stepping as numerical scheme, which has already constructed its kernel calls.
guard	str C++ boolean expression, evaluated per cell in touchCellFirstTime.

Member Function Documentation

◆ get_action_set_name()

exahype2.api.rkfd4.actionsets.ComputeMaxEigenvalue.ComputeMaxEigenvalue.get_action_set_name ( self )

You should replicate this function in each subclass, so you get meaningful action set names (otherwise, it will be AbstractRKFD4ActionSet0,1,2,...).

Reimplemented from exahype2.api.rkfd4.actionsets.AbstractRKFD4ActionSet.AbstractRKFD4ActionSet.

◆ get_body_of_operation()

exahype2.api.rkfd4.actionsets.ComputeMaxEigenvalue.ComputeMaxEigenvalue.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.

Here is the caller graph for this function:

◆ get_guard_of_operation()

exahype2.api.rkfd4.actionsets.ComputeMaxEigenvalue.ComputeMaxEigenvalue.get_guard_of_operation	(	self,
		operation_name
	)

Return the guard of an operation.

The guard is a C++ boolean expression. The body of the operation (see get_body_of_operation()) is executed if and only if the guard holds. The guard can use the same arguments as the body, i.e. the marker and the fine and coarse grid data. By default, the guard is true, i.e. the body is always executed.

See class' string constants starting with OPERATION_ for possible values of operation_name.
