create_compute_new_time_step_size()

exahype2.solvers.FixedSubcyclingTimeSteppingCodeSnippets.FixedSubcyclingTimeSteppingCodeSnippets.create_compute_new_time_step_size

(

self

)

This is global, fixed time stepping, i.e.

the new time step size will likely be the same as the previous one, unless the mesh changes, as we work with normalised time step sizes, i.e. in this case the time step size might change. Anyway, the new time step size is only for stats anyway, as we'll pick a global one when we determine timeStepSize the next time step.

create_compute_time_step_size()

exahype2.solvers.FixedSubcyclingTimeSteppingCodeSnippets.FixedSubcyclingTimeSteppingCodeSnippets.create_compute_time_step_size

(

self

)

Within the actual compute kernels, the kernels ask the solver variant how to determine a new field.

const double timeStepSize = ...;

You can remove the const if you want. Anyway, this routine has to build up the right time step size choice.

create_finish_time_step_implementation()

exahype2.solvers.FixedSubcyclingTimeSteppingCodeSnippets.FixedSubcyclingTimeSteppingCodeSnippets.create_finish_time_step_implementation

(

self

)

This routine is inserted after we have reduced all global quantities.

These are the quantities with the postfix ThisTimeStep.
