problems in uniax.py
Hello:
I have some problems in the example uniax.py.
1. I found the number (by the command 'print len(O.bodies)') in the cell isn't the same as the value appointed by sphereInCell. When I change the shape of the packing (i.e. the values in pack.inHyperbol
2. How to prepare a 2D packing using pack.randomDens
Any kind of help is appreciated. Thanks.
Here is the scripts and error:
