Detailed Description
Trigger a slab size change.
The new size will be the minimum suggested by any of the provided step choosers on any element. This requires a global reduction, so it is possible to delay the change until a later slab to avoid a global synchronization. The actual change is carried out by Actions::ChangeSlabSize.
When running with global time-stepping, the slab size and step size are the same, so this adjusts the step size used by the time integration. With local time-stepping this controls the interval between times when the sequences of steps on all elements are forced to align.
