Calculate Normals based on Initial Particles?
So I am trying to do something which I think might be out of the scope of the current DualSPHysics capabilities. Basically I have a sinus sloped profile as such:
And I want to use the new Modified Dynamic Boundary Condition (MDBC) to simulate. The problem is that when I run the simulation I get the warning:
1. The selected DDT '(Fourtakas et al 2019 (full)' needs several boundary layers when h/dp>1.5
2. There are 7162 of 8071 fixed or moving boundary particles without normal data.
Where I dont understand the first warning, but it always pops up, but the 2nd one is what I am dealing with right now, since I was hoping there might be a way for me to easily upload normal data for my sloped profile? My sloped profile has a "width" of 2 particles:
But maybe I should have more particles also in the width? I hope someone can help me out.
