create_volumetric_solver_call()

			solver_variant )

A set of default volumetric kernel calls.

You might want to use different solver calls in your code depending on the context.

Difference to Finite Volume (FV) implementation

In the FV code base, I need the implementation routines as argument: As we work with FV, the generic FV class does not know which implementations are around. If you work with a domain-specific Rusanov solver, e.g., then there is no such thing as an ncp.

For the DG schemes, things are different: Every DG solver in ExaHyPE 2 in principle supports the ncp. So the base Python class already instantiates the corresponding dictionary entries, and we can use them straightaway.

Arguments

solver_variant: SolverVariant Picks different implementation variants
