[Yade-users] [Question #675496]: ymport textExt attrs
New question #675496 on Yade:
https://answers.launchpad.net/yade/+question/675496
Hello everyone!
I am trying to use a pre created agglomerate in a compression test. For this I
use export and ymport textExt.
In the creating script I use after creating my aggregate :
part =
export.textExt('Agregado2.txt',format='x_y_z_r_attrs',attrs=['b.material.normalCohesion',
'b.material.shearCohesion'])
The file created contains all properties I need. Everything is working fine
until here.
Although, when I import the aggregate in the compression script, spheres don't
present the attrs that I exported before. I am using:
aggregate = ymport.textIExt('Agregado2.txt', material = CohFrictMat(), format =
'x_y_z_r_attrs', attrs=['b.material.normalCohesion',
'b.material.shearCohesion'])
O.bodies.append(aggregate)
The spheres imported has CohFrictMat() material but the normalCohesion and
shearCohesion are equal to -1 (would it be the default value?).
I would like to know if it is possible to export and import the normal and
shear Cohesion. If it is possible, am I doing something wrong? Why my final
script doesn't import the attrs that I have exported?
Many thanks!
Bruna.

[Yade-users] [Question #403777]: Breakage bibliography and examples
New question #403777 on Yade: https://answers.launchpad.net/yade/+question/403777 Hi all. I am trying to simulate breakage of particles in yade. I am having some troubles because I am unable to make particles formed by agglomerates that breaks under defined condition. One of my problems is that I am not able to apply different interactions between the particles of the sample and the spheres that form one particle. Does the yade accept two or more types of interaction in the same simulation? If yes, how could I define that a number of spheres is my particle and make it interact with other particles also formed by a number of particles? Is there any recomended bibliography that I can follow to try making the breakage of particle formed by agglomerates? Also is there any examples that somebody has already made?

New question #309164 on Yade: https://answers.launchpad.net/yade/+question/309164 Hello everyone! I'm trying to simulate a shear teste using yade. I want to track the forces in the shear band. For this I thought I could position a plan in the middle of my sample and measure the forces in this plan. However when I put this plan in the simulation it interacts with the spheres. In the manual there is 'sense' that allows me to set interactions in negative side, positive side or both sides of the plan (utils.wall) but it doesn't gives me the option of interactions in none. My question is if there is a manner to measure the forces in a virtual plane in the middle of my sample. Putting a plan (utils.wall) is an option? If yes, is it possible to set this plan so that it doesn't interacts with my spheres?

I have created a script where I deposite spheres using the CircularFactory engine so that I can have a specif PSD that represents my material. Although, I want to test how the shape influences the sample so I'm trying to create clumps with the spheres that I have already created. When I clump them using replaceByClumps, the sample seems to explode. I think this happens because the spheres that will form the clumps are not close together so they looks for another sphere that will follow the rule of the template that I have created making a mess in the sample. Maybe if it's possible just to clump two or three spheres that is next to the other this problem would be solved. So my question is if there is a way to clump a specific number of spheres that are just next to the other without been necessary list the relation between their radius. Thanks a lot.
