How to "fillNeighbors" for particles with the symmetrical boundary condition

[Horizonatpku]

Hi everyone,

I have read the TEST case NeighborParticles.

[amrex/Tests/Particles/NeighborParticles

This case builds the neighbor list for particles with periodic boundary condition (b.c.):

int is_per[] = {AMREX_D_DECL(params.is_periodic, params.is_periodic, params.is_periodic)};

However, other type b.c. are usually in many applications, such as the symmetrical boundary condition
Could you please help me with build the neighbor list for various kinds of b.c.

Thanks a lot!

Hi Yifeng He,

If what you want to do is have the neighbor particles filled with, e.g. reflected copies of particles near the domain boundaries, then that is currently not supported and would have to be implemented. However, if you're interested in implementing this, I can point to where in the NeighborParticle class you'd need to make the changes.
