[Yade-users] [Question #279359]: MakeCloud() single-threaded?

[Gary Pekmezi]

New question #279359 on Yade:
https://answers.launchpad.net/yade/+question/279359

I noticed that when I run a triaxial test (either with a preprocessor or a 
script), TriaxialStressController() and TriaxialCompressionEngine() make use of 
all the cores specified via the -jN command. However, MakeCloud() is using a 
single core. Is this inherent to the algorithm?

Thanks,
Gary

Hi Behzad,

another option is to send us "pull request" or just a

Hi Behzad,

See https://yade-dem.org/doc/github.html
However, in your case the issue might be this line: 
"This direct access to trunk [...] is only possible for members of the git team 
“developpers”. Send an email at yade-...@lists.launchpad.net to join this team

[Yade-users] [Question #279391]: how to commit a change?

[behzad]

New question #279391 on Yade:
https://answers.launchpad.net/yade/+question/279391

Hi folks,

I made a new class of materials with viscoelastic behavior. It's actually 
Burger's model. Interactions of CohBurgersMat with CohFrictMat and also 
FrictMat has been also defined in the model.

CohbugersMat-CohbugersMat interactions and also CohbugersMat-CohFrictMat 
interactions have been tested and verified.

The model obviously needs more trimming so I'd like to make it public so we can 
improve it. 

I was not able to commit the changes directly on github, using git push command.

How can I commit this model?

Thanks,
Behzad

be careful, that all commands are case sensitive, so sphere and Sphere are
completely different things :-) Sphere is a class inherited from Shape.
utils.sphere(...) is auxiliary function to create Body, whose shape is
Sphere:

#
s = sphere((0,0,0),1)
print s
print s.shape
#

Even if the name would be the same, the different "namespace" (yade.wrapper
or yade.utils) means, that it is different thing. you can try

###
utils.Sphere = utils.sphere
print utils.Sphere
print yade.wrapper.Sphere
###

In the example, "s" is instance of Body. Body has attributes e.g. state,
shape etc. s.shape can be any shape, but if it is created by utils.sphere
functions, s.shape is Sphere, and it has radius (you can find Sphere in
class reference). Also see my above comments

It is a dangerous solution. I would recommend you to use
"-DCMAKE_INSTALL_PREFIX=" option without "sudo".

Hi everyone,

I'm trying to simulate clump interactions using version 1.20 of YADE and this

why?

hello Jan
thatns you for your consideration

my reference Documentation link:
https://yade-dem.org/doc/Yade.pdf

there are some more ambiguities:

about question 1- : there are some functions in Class references(ch 8) that are 
repeated in Yade modules (ch9); although they are not the same but i can not 
understand the difference for a better selecting when coding:
  class yade.wrapper.Sphere((object)arg1) (p.156)
   yade.utils.sphere(center, radius, dynamic=None, fixed=False,   
wire=False, color=None, highlight= False, material=-1, mask=1)  (p. 464)

again such classes could be found about 'tetra'. what is the difference
between s1 (an instance of  yade.wrapper.Sphere) and s2(an instance of
yade.utils.sphere)

2- i found this example on page 6:
Yade [96]: s=utils.sphere(center=[0,0,0],radius=1)
...
Yade [99]: s.shape.radius
...
as i have searched there is no 'radius' method for 'shape' class (p 151).  how 
above command is correct?

thanks Jan
