New question #680907 on Yade:
https://answers.launchpad.net/yade/+question/680907
I want to write a data-post class for the result from yade. In my class i used
the Sphere class. But when i invoke my class in yade console, the Sphere class
is not recognised. I have looked up the information about Importing Yade in
other Python applications. It says as following,
$ cd /path/where/you/want/yadeimport
$ ln -s /path/to/yade/executable/yade-trunk yadeimport.py
But when i do the second step, the error comes as "operation is not supported".
Here is my code,
for my class file named “yadedatapost.py”
import numpy as np
import os
from yadeimport import *
class yadeDataPost:
def __init__(self):
pass
def erase_outbox_sphere(self):
for eb in O.bodies:
if isinstance(eb.shape, Sphere):
O.bodies.erase(eb.id)
Then i start yade from terminal, input the following code,
import sys
sys.path.append('/mnt/hgfs/virpc/backup')
from yadedatapost import yadeDataPost
dp1 = yadeDataPost()
dp1.erase_outbox_sphere()
The error comes, No Sphere defined. I know the critical step of creating a
symbolic link is missing.
Thanks.

The engine is not responsible for the dynamics of the system. Turning the engine to dead means the RotationEngine is no longer setting an angularVelocity to the body. But the body still exists and still has an angular velocity. I guess you are looking for something more along the lines of: def motion_5(): O.engines[11].angularVelocity=0 O.engines[11].angularVelocity=0 If you want to set the angularVelocity to 0 for a set of bodies.

Re: [Yade-users] [Question #680888]: how creat a tansparent polyhedra
Question #680888 on Yade changed: https://answers.launchpad.net/yade/+question/680888 Jan Stránský proposed the following answer: Hi, Next time, please be more specific: - transparent in Yade GUI? Paraview? - haw do you create your polyhedrons? a MWE with one polyhedron displaying it would be nice.. Assuming Yade GUI: transparency is controlled by body.shape.wire attribute. Set it to True to see "wireframe". It is not only edges, but also triangulation of more-than-tree-vertex faces. some functions accepts wire argument (like utils.polyhedron), some not (like those in polyhedra_utils module) ### from yade import polyhedra_utils, qt mat = defaultMaterial() p1 = polyhedra_utils.polyhedra(mat) # no parameter 'wire' #p1.wire = ... must be set "manually" p2 = utils.polyhedron(((0,0,0),(1,0,0),(0,1,0),(1,1,0),(0,0,1)),wire=True) # you can set wire at creation O.bodies.append((p1,p2)) qt.View() # uncomment to "flip" transparency #p1.shape.wire = True #p2.shape.wire = False ### cheers Jan -- You received this question notification because your team yade-users is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
