Does the latest version deal with that or is it a real bug?
Hi Luc, thanks for reporting. The fix is trivial, it will land in trunk
with my next commit. If you need the fix in yoru version, go to
Shop::{unbalancedForce,kineticEnergy} and in the FOREACH loop, change
if(!b-isDynamic())
I used to get errors described below. For those, who have the same problem,
just change
self.setRange(int(-1e10),int(1e10)); self.setSingleStep(1);
to
self.setRange(int(-1e9),int(1e9)); self.setSingleStep(1);
in ../lib/yade-trunk/py/yade/qt/SerializableEditor.py
I will change it in the

Hi Anton,
read https://www.yade-dem.org/sphinx/user.html#checkpoints -- although it
talks about loadTmp, the same applies to O.pause() etc. Calling O.pause()
from inside the engine will (though it might depend on exact timing between
python and computation threads, and that is probably the reason
Instead of using BREP, is it possible to import geometries from
AutoCAD/GAMBIT into Yade-0.50 running on Kubuntu?
There is no direct import (see
https://yade-dem.org/sphinx/yade.ymport.html for what is available); it
depends on what kind of data you want to import. I would suggest that you
I want to delete some facet during simulating process. Are there
some functions in yade or I make the code for this purpose? Thanks
This functionality is provided, see
https://yade-dem.org/sphinx/prog.html#insertion-deletion (the python
example: O.bodies.erase(id)); it is not documented in the
are there some commands (functions) in yade for rotating the
surface (gts surface)? thanks.
Hi,
such func is in the gts (http://pygts.sf.net) module itself, whcih is
included with Yade and also documented:

I have a question on how to import a module into a python script to be
run with Yade. I do all as it should be, but apparently if in the
script I include the line import myNameModule, on the console it says
that module myNameModule not found. OTHT, if I do not include this
line in the script,
this should be easy in yade, but I can't spot the easy solution that
must be there. I have beads in a container. I want to model their
friction against it's walls. I can get the friction of the beads
themselves by measuring the angle of internal friction. assuming I
know the poissons
Hello all,
I ran the example of funnel.py
(revision2389:http://bazaar.launchpad.net/~yade-dev/yade/trunk/annotate/head%3A/examples/funnel.py).
The properties of spheres can be changed through
O.bodies.append([utils.sphere(c,r,material=ElastMat(young=1e9,density=3e3,...))
for c,r
I would like to know how to visualise force chains. There was an
email suggesting that we can render it using glyph-cylinders. But I
can't get it to work.The intr saves forces in type cellData (not
pointData).
Hi, it is explained in
