Description

For example, scalar advection and hyperbolic diffusion have constant propagation speeds, thus the time step needs to be calculated only once after each change of the mesh. This can be a performance improvement, especially when doing parallel simulations, where it saves one blocking collective communication per time step.

For this to work, first #215 needs to be resolved.
