Hi DualSPHysics developers:
May I get some advice from you all on the data structure of DualSPHysics?
I have 3 questions:
From example: Let's assume we have an array called "velrhop" in DualSPHysics & I'm accessing this value, i.e. velrhop .
Regarding the number "12" inside the square bracket , does it really refer to the particle ID marked as "12" in DualSPHysics?
From the array say "velrhop [i]", what should we do in order to identify the boundary particles from the index i ?
Is the index of boundary particles stored first in velrhop, followed by those of fluid particles?
While doing particle summation operation (say computing the "boundary" pressure forces acting on a fluid particle i), we need to scan through the neighbors "j" of particle "i", based on the pressure array say p [i].
As such, how to identify whether p[j] refers to fluid OR boundary particle pressure?
Thanks in advance.
