Why use "Fourtakas (full)" in DDT?
Under examples/other/freedraw mode there is a case called "CaseFrBeach". It outputs this warning:
"1. The selected DDT '(Fourtakas et al 2019 (full)' needs several boundary layers when h/dp>1.5"
Why do I use "full" option for DDT in this case and how do I know I have enough boundary layers?
