Dear Vaclav,

Following your suggestion, I read through the detailed manual, which is really helpful.

I have run a few cases and learned the basic principles of Woo.

For the examples/densepack.py, I wonder if you could point me to the reference you were using to create the random packing. Apologies if I missed the reference in your manual or in the source code. I would like to learn a bit more about how to create the dense pack.

Your kind help is much appreciated.

Dear Vaclav,

Many thanks for your answer and updating the documentation. Apologies for my belated response, too.

However, I still have a few questions:

All of these are implemented in the

randomDensePack2singleCell as pointed out very kindly by you through the following engines.Indeed, I found there are many particles overlapping each other through checking the distance between particles. I wonder if this overlapping results from the initial packing process that starts with randomly generated particles (how about this algorithm?) with overlaps in the space.

As you have pointed out, the overlap-free might be achieved through woo.dem.Law2

L6GeomFrictPhys_IdealElPl.iniEqlb, I checked that it is used in the ell0.py exampleI would like to use this to replace the original S.engines. I wonder if you would be kind enough to add another version of

randomDensePack2singleCell using woo.dem.Law2L6GeomFrictPhys_IdealElPl.iniEqlb.In addition, I wonder if it is possible to save the intermediate data of the packing process as I would like to use an animation to see the packing dynamic process (Maybe I need to go back to your detailed manual to find this out).

Finally, Many thanks for your help and kindness in advance.

Best D
