Particle arrangement

[6tang12]

When using ParticleDict to define particle arrangement, how can I place particles in the shape of a frustum?

only cube, sphere, and cylinder is possible. If you want to place them in frustum order, write a python program, save the x y z position of particles in a file, and then import particles positions in the simulation (using particlesDict).

{
    method file;
    fileInfo
    {
           name    nameOfTheFile;
           commaSeparated  No; // Yes, or No
    }
}

nameOfTheFile that contains particle position data in the root folder the simulation. The content of the file is something like this:
x1 y1 z1
x2 y2 z2
x3 y3 z3
x4 y4 z4

I tried, but it’s easy to get a segmentation fault (core dumped) error.

attach the setup files of your case to see find the problem.
