Allocations in RelaxationCallback

DispersiveShallowWater.jl/src/callbacks_step/relaxation.jl

Lines 82 to 84 in 55b6cc6

	function convex_combination(gamma, uold, unew)
	@. uold + gamma * (unew - uold)
	end

This will allocate new vectors whenever it's called. That's of course totally fine for now but may slow down the process a bit when you use bigger state vectors (increased grid refinement).

Ok, thanks. I'll keep that in mind and fix it once it seems necessary.
