spheres/spheres3.c

This 3D example program randomly generates parallel distributed sets of 3D sphere shells and refines all quadrants of a 3D forest intersecting any of the cells. It compiles from the same code as the 2D example spheres/spheres2.c with minimal redefinitions (please see a more detailed description there). In this sense, the code is mostly dimension independent.

Usage: p8est_spheres with the following options:

*    -l | --minlevel  <INT>       Lowest level
*    -L | --maxlevel  <INT>       Highest level
*    -r | --rmax      <REAL>      Max sphere radius
*    -t | --thickness <REAL>      Relative sphere thickness
*    -f | --lfraction <REAL>      Length density of spheres
*    -s | --spherelems <REAL>     Min elements per sphere diameter
*    -N | --nbottom   <INT>       Notify bottom multiplicator
*    -A | --alltoall  <BOOLEAN> Notify alltoall implementation
*    -S | --scaling   <BOOLEAN> Configure for scaling test
*    -R | --repetitions <INT>     Repeat run multiple times
*    -V | --write-vtk <BOOLEAN> Output VTK files
*    -P | --prefix    <STRING>    Prefix for file output
