Luc Scholtès proposed the following answer:
Hi Jerome,

You are absolutely right, the solutions provided in the capillary files
correspond to a wetting angle of 0 degrees.

It should be written in the documentation... Could you rectify that?

Many thanks to Pro. Jan.
The geometrical shape of the block is complicated and not convex polyhedron. So 
the polyhedron body is not suitable for this simulation.
Thanks  a lot!

[Yade-users] [Question #254731]: cohesion

2014-09-19 Thread Ferenc Safranyik
New question #254731 on Yade:
https://answers.launchpad.net/yade/+question/254731

Hi all,

please help me, I'm a new user in yade. My problem is: I want to make a 
simulation with cohesive soil. First I made all of  the simulation (the 
particles, and the motions) with frictmat and it was work. Then I modified the 
material to cohfrictmat (Ig2, Ip2, Law2 also), I set 
Ip2_CohFrictMat_CohFrictMat_CohFrictPhys.setCohesionNow =True, but I get the 
error message: Segmentation fault (core dumped).
What can be the problem? 

Thanks a lot!

Hello all, 

Is there any implemented code that calculates the volume of overlap in one 
interaction between spheres and sphere-facet interaction (for all interactions)?

Jérôme Duriez proposed the following answer:
Hi,

Presenting your script would be necessary to get some help, here.
Another method, maybe more straightforward, is to launch a debug version of 
yade, so that you will get more info with the Segmentation fault message. To 
obtain such debug version, you need to use a yade executable, compiled from 
source with -DDEBUG = ON. See https://yade-dem.org/doc/user.html#crashes

[Yade-users] [Question #254747]: Labelling engines after reload

2014-09-19 Thread Jérôme Duriez
New question #254747 on Yade:
https://answers.launchpad.net/yade/+question/254747

Hi, I apologize in advance for this weird question, but... 
I have different xml files (obtained successively during a first yade session, 
but I do not know if this matters). During a second Yade session (current trunk 
version), I got different results with the three following lines :

O.load('save_i.xml')
O.engines=[NewtonIntegrator(label='newt')] # the choice of the engine does not 
matter
print newt

Most of the time, I got an error : NameError: name 'newt' is not defined. It 
works (NewtonIntegrator instance at 0x686d240) only with one save, the 
first one that was obtained in the procedure of the first Yade session (still, 
does it matter ?).

Does someone understand something ? I got mad with labelling engines... Thanks 
a lot,

Jerome

PS : at the moment I can not precise a simple procedure to generate such 
problematic xml saves. Mines were obtained during continuous isotropic 
unloading, for sample generation (and are around 150 MB)
