How to solve the staircase boundary problem?
edited September 2016
I want to establish a curve wall, and I found the curve wall created by DualSPHysics like staircase and quite rough. How can I solve this problem? Any help will be appreciated.
We are now working on new GenCase, so that next version will allow to create particles at the locations the user need instead of using the 3D cartesian grid.
Next releases will include this option, but now there is no solution for you. The only way is that you code your own initial state of the particles to create the .bi4 file.
I still have this problem, my version of dualSphysics is 4.2. Does it have a new tool to solve this trouble? Thank you.
In v4.2 we have included new options, like the one shown in the example RotatedBox.

But I am afraid that this example is still not what you need. I am so sorry.
We will work on new functionalities that allows to create particles at any exact position defined by the user (like a curve) instead of points in the 3-D lattice
Thank you for your answer and all the work on dualSphysics.
I import a complex geometry from a stl, so use the rotate tool isn't possible in my case.
Waiting for this new functionalities, I have a new question in order to reduce this staircase problem. When we decline dp, this problem is smaller, but the computation time is too big. It is possible to define differents dp for the boundary and the fluid? (using the mk or the type?)
(and sorry for my english if it isn't totally exact)
That functionality is not available now, but we are also working on that.
