Hello,
I am simulating the filling of a box with a large number of particles (10^5 to 10^6): first I insert the particles in a bigger volume and then I let them pack under the action of gravity.
Which is the best choice of processors to parallelize it? I would like that the Z axis is divided into non-constant grid sizes... e.g., so that more processors compute the particles at the bottom of the box and only 1-2 at the top (when the particles will stay for only a short time before packing).
Do you have any suggestion?
Thanks a lot,
