Status: Open => Answered
Jérôme Duriez proposed the following answer:
Hi,
This message ("No suitable packing in database found, running PERIODIC
compression") is not an error, it just tells you that randomDensePack()
has to run a hidden simulation to give you a packing (instead of picking
a previously generated packing in the database ie your Yade-use history)
This being said, it's a little sad you mention to us some working
commands, but not the actual commands (in a MWE shape, see [*]) that are
problematic to you. As it is now, it is very difficult to understand and
help with your problem.
Note that a function like O.bodies.append() is always necessary after
calling randomDensePack() for the particles to be defined in the
simulation (and displayed in the 3D view)
Jerome

Description changed to:
Hi,
When I conduct simulation using randomDensePack in YADE(vision 1.20.0), a
strange error occur as follows:
Welcome to Yade 1.20.0
TCP python prompt on localhost:9000, auth cookie `caseus'
XMLRPC info provider on http://localhost:21000
[[ ^L clears screen, ^U kills line. F12 controller, F11 3d view (use h-key for
showing help), F10 both, F9 generator, F8 plot. ]]
Yade [1]: from yade import pack
Yade [2]: ## construct the predicate first
Yade [3]:
pred=pack.inHyperboloid(centerBottom=(0,0,-.1),centerTop=(0,0,.1),radius=.05,skirt=.03)
Yade [4]: ## alternatively:
pack.inHyperboloid((0,0,-.1),(0,0,.1),.05,.03)
Yade [5]: ## pack the predicate with spheres (will be explained later)
Yade [6]: spheres=pack.randomDensePack(pred,spheresInCell=2000,radius=3.5e-3)
No suitable packing in database found, running PERIODIC compression
/usr/lib/x86_64-linux-gnu/yade/py/yade/pack.py:296: FutureWarning: The default
behavior will change; specify returnSpherePack=True for the new behavior, and
False to get rid of this warning (your code will break in the future, however).
The returned SpherePack object can be added to the simulation using
SpherePack.toSimulation()
warnings.warn('The default behavior will change; specify
returnSpherePack=True for the new behavior, and False to get rid of this
warning (your code will break in the future, however). The returned SpherePack
object can be added to the simulation using
SpherePack.toSimulation()',category=FutureWarning)
Yade [7]: ## add spheres to simulation
Yade [8]: O.bodies.append(spheres)
-> [8]:
[0,
1,
2,
3,
4,
5,
Finally, Yade got a same results as in the tutorial, but when I using
randomDensePack to conduct other simulation, it got only this error (No
suitable packing in database found, running PERIODIC compression...) without
any particles displayed in the 3D view.
Can you help me to solve this problem?
Many thanks.
